5 Data Sheet GENERAL DESCRIPTION The are high speed, digital-to-analog video encoders in a 64-lead LQFP package. Six high speed, 3.3 V, -bit video DACs provide support for composite (CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs in standard definition (SD), enhanced definition (ED), or high definition (HD) video formats. The have a 24-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over an SDR interface, and ED/HD video formats are supported over SDR and DDR interfaces. Pixel data can be supplied in either the YCrCb or RGB color spaces. The parts also support embedded EAV/SAV timing codes, external video synchronization signals, and I 2 C communication protocol. In addition, simultaneous SD and ED/HD input and output are supported. Full-drive DACs ensure that external output buffering is not required, while 26 MHz (SD and ED) and 297 MHz (HD) oversampling ensures that external output filtering is not required. Cable detection and DAC autopower-down features keep power consumption to a minimum. Table lists the video standards directly supported by the. Table.

28 MPU PORT DESCRIPTION Devices such as a microprocessor can communicate with the through a 2-wire serial (I 2 C-compatible) bus. After power-up or reset, the MPU port is configured for I 2 C operation. I 2 C OPERATION The support a 2-wire serial (I 2 C-compatible) microprocessor bus driving multiple peripherals. This port operates in an open-drain configuration. Two wires, serial data (SDA) and serial clock (SCL), carry information between any device connected to the bus and the. The slave address of the device depends on the device (ADV7342 or ADV7343), the operation (read or write), and the state of the ALSB pin ( or ). See Table 6, Figure 47, and Figure 48. The LSB sets either a read or a write operation. Logic corresponds to a read operation, and Logic corresponds to a write operation. A is controlled by setting the ALSB pin of the ADV7342/ ADV7343 to Logic or Logic. Table 6. I 2 C Slave Addresses Device ALSB Operation Slave Address ADV7342 Write xd4 Read xd5 Write xd6 Read xd7 ADV7343 Write x54 Read x55 Write x56 Read x57 A X ADDRESS CONTROL SET UP BY ALSB Figure 47. ADV7342 I 2 C Slave Address A X ADDRESS CONTROL SET UP BY ALSB Figure 48. ADV7343 I 2 C Slave Address READ/WRITE CONTROL WRITE READ READ/WRITE CONTROL WRITE READ Analog Devices, Inc., recommends tying up ALSB. If this is not done, a power supply sequence (PSS) may be required. For more information on the PSS, see the Power Supply Sequencing section. The various devices on the bus use the following protocol. The Data Sheet master initiates a data transfer by establishing a start condition, defined by a high-to-low transition on SDA while SCL remains high. This indicates that an address/data stream follows. All peripherals respond to the start condition and shift the next eight bits (7-bit address plus the R/W bit). The bits are transferred from MSB down to LSB. The peripheral that recognizes the transmitted address responds by pulling the data line low during the ninth clock pulse. This is known as an acknowledge bit. All other devices withdraw from the bus at this point and maintain an idle condition. The idle condition occurs when the device monitors the SDA and SCL lines waiting for the start condition and the correct transmitted address. The R/W bit determines the direction of the data. Logic on the LSB of the first byte means that the master writes information to the peripheral. Logic on the LSB of the first byte means that the master reads information from the peripheral. The act as a standard slave device on the bus. The data on the SDA pin is eight bits long, supporting the 7-bit addresses plus the R/W bit. It interprets the first byte as the device address and the second byte as the starting subaddress. There is a subaddress auto-increment facility. This allows data to be written to or read from registers in ascending subaddress sequence starting at any valid subaddress. A data transfer is always terminated by a stop condition. The user can also access any unique subaddress register on a one-by-one basis without updating all the registers. Stop and start conditions can be detected at any stage during the data transfer. If these conditions are asserted out of sequence with normal read and write operations, they cause an immediate jump to the idle condition. During a given SCL high period, the user should issue only a start condition, a stop condition, or a stop condition followed by a start condition. If an invalid subaddress is issued by the user, the do not issue an acknowledge but return to the idle condition. If the user uses the auto-increment method of addressing the encoder and exceeds the highest subaddress, the following actions are taken: In read mode, the highest subaddress register contents are output until the master device issues a no acknowledge. This indicates the end of a read. A no acknowledge condition occurs when the SDA line is not pulled low on the ninth pulse. In write mode, the data for the invalid byte is not loaded into any subaddress register, a no acknowledge is issued by the, and the parts return to the idle condition. Figure 49 shows data transfer for a write sequence and the start and stop conditions. Figure 5 shows bus write and read sequences. Rev. D Page 28 of 8

30 REGISTER MAP ACCESS A microprocessor can read from or write to all registers of the via the MPU port, except for registers that are specified as read-only or write-only registers. The subaddress register determines which register the next read or write operation accesses. All communication through the MPU port starts with an access to the subaddress register. A read/write operation is then performed from/to the target address, which increments to the next address until the transaction is complete. Data Sheet REGISTER PROGRAMMING Table 7 to Table 35 describe the functionality of each register. All registers can be read from as well as written to, unless otherwise stated. SUBADDRESS REGISTER (SR7 TO SR) The subaddress register is an 8-bit write-only register. After the MPU port is accessed and a read/write operation is selected, the subaddress is set up. The subaddress register determines to or from which register the operation takes place. Table 7.

The CrCb pixel data is input on Pin Y7 to Pin Y (or Pin C7 to Pin C, depending on Subaddress x, Bit 7), with Pin Y/C being the LSB. Embedded EAV/SAV timing codes are not supported, so an external synchronization is needed in this mode. 24-Bit 4:4:4 RGB Mode Subaddress x87, Bit 7 = In 24-bit 4:4:4 RGB input mode, the red pixel data is input on Pin S7 to Pin S, the green pixel data is input on Pin Y7 to Pin Y, and the blue pixel data is input on Pin C7 to Pin C. The S, Y, and C pins are the respective bus LSBs. Embedded EAV/SAV timing codes are not supported with SD RGB mode. In addition, master timing mode is not supported for SD RGB input mode; therefore, external synchronization must be used. Table 36.

52 DESIGN FEATURES OUTPUT OVERSAMPLING The include two on-chip phase-locked loops (PLLs) that allow for oversampling of SD, ED, and HD video data. Table 4 shows the various oversampling rates supported in the. SD Only, ED Only, and HD Only Modes PLL is used in SD only, ED only, and HD only modes. PLL 2 is unused in these modes. PLL is disabled by default and can be enabled using Subaddress x, Bit =. External Sync Polarity For SD and ED/HD modes, the parts typically expect HS and VS to be low during their respective blanking periods. However, when the CEA86 compliance bit is enabled (x39, Bit 5 for ED/HD modes and x86, Bit 3 for SD modes), the part expects the HS or VS to be active low or high, depending on the input format selected (x3 Bits [7:3]). Data Sheet If a polarity other than the default is needed for ED/HD modes, x3a Bits [2:] can be used to invert PHSYNCB, PVSYNCB or PBLANKB individually, regardless of whether CEA-86-B mode is enabled. It is not possible to invert S_HSYNC or S_VSYNC. SD and ED/HD Simultaneous Modes Both PLL and PLL 2 are used in simultaneous modes. The use of two PLLs allows for independent oversampling of SD and ED/HD video. PLL is used to oversample SD video data, and PLL 2 is used to oversample ED/HD video data. In simultaneous modes, PLL 2 is always enabled. PLL is disabled by default and can be enabled using Subaddress x, Bit =. Table 4.

53 Data Sheet HD INTERLACE EXTERNAL P_HSYNC AND P_VSYNC CONSIDERATIONS If the encoder revision code (Subaddress xbb, Bits[7:6]) = or higher, the user should set Subaddress x2, Bit to high to ensure exactly correct timing in HD interlace modes when using the P_HSYNCand P_VSYNC synchronization signals. If this bit is set to low, the first active pixel on each line is masked and the Pr and Pb outputs are swapped when using the YCrCb 4:2:2 input format. Setting Subaddress x2, Bit to low causes the encoder to behave in the same way as the first version of silicon (that is, this setting is backward compatible). If the encoder revision code (Subaddress xbb, Bits[7:6] =, the setting of Subaddress x2, Bit has no effect. In this version of the encoder, the first active pixel is masked and Pr and Pb outputs are swapped when using the YCrCb 4:2:2 input format. To avoid these limitations, use the newer version of silicon or a different type of synchronization. These considerations apply only to the HD interlace modes with external P_HSYNCand P_VSYNC synchronization (EAV/SAV mode is not affected and always has exactly correct timing). There is no negative effect in setting Subaddress x2, Bit to high, and this bit can remain high for all the other video standards.

In this state, the horizontal and vertical counters remain reset. When this bit is set back to, the internal counters resume counting. This timing reset applies to the ED/HD timing counters only. SD SUBCARRIER FREQUENCY LOCK Subcarrier Frequency Lock (SFL) Mode In this mode (Subaddress x84, Bits[2:] = ), the ADV7342/ ADV7343 can be used to lock to an external video source. The SFL mode allows the to automatically alter the subcarrier frequency to compensate for line length variations. When the part is connected to a device such as an ADV743 video decoder (see Figure 59) that outputs a digital data stream in the SFL format, the part automatically changes to the compensated subcarrier frequency on a line-by-line basis. This digital data stream is 67 bits wide, and the subcarrier is contained in Bit to Bit 2. Each bit is two clock cycles long.

54 SD VCR FF/RW SYNC Subaddress x82, Bit 5 In DVD record applications where the encoder is used with a decoder, the VCR FF/RW sync control bit can be used for nonstandard input video, that is, in fast forward or rewind mode. In fast forward mode, the sync information at the start of a new field in the incoming video usually occurs before the correct number of lines/fields is reached. In rewind mode, this sync signal usually occurs after the total number of lines/fields is reached. Conventionally, this means that the output video has corrupted field signals because one signal is generated by the incoming video and another is generated when the internal line/field counters reach the end of a field. When the VCR FF/RW sync control is enabled (Subaddress x82, Bit 5), the line/field counters are updated according to the incoming VSYNC signal and when the analog output matches the incoming VSYNC signal. This control is available in all slave-timing modes except Slave Mode. VERTICAL BLANKING INTERVAL Subaddress x3, Bit 4; Subaddress x83, Bit 4 The are able to accept input data that contains VBI data (such as CGMS, WSS, and VITS) in SD, ED, and HD modes. If VBI is disabled (Subaddress x3, Bit 4 for ED/HD; Subaddress x83, Bit 4 for SD), VBI data is not present at the output and the entire VBI is blanked. These control bits are valid in all master and slave timing modes. For the SMPTE 293M (525p) standard, VBI data can be inserted on Line 3 to Line 42 of each frame or on Line 6 to Line 43 for the ITU-R BT.358 (625p) standard. VBI data can be present on Line to Line 2 for NTSC and on Line 7 to Line 22 for PAL. In SD Timing Mode (slave option), if VBI is enabled, the blanking bit in the EAV/SAV code is overwritten. It is possible to use VBI in this timing mode as well. If CGMS is enabled and VBI is disabled, the CGMS data is, nevertheless, available at the output. SD SUBCARRIER FREQUENCY CONTROL Subaddress x8c to Subaddress x8f The are able to generate the color subcarrier used in CVBS and S-Video (Y-C) outputs from the input pixel clock. Four 8-bit registers are used to set up the subcarrier frequency. The value of these registers is calculated using Subcarrier Frequency Number of Register = Number of subcarrier periods in one video line 27 MHz clk cycles in one video line 2 32 For example, in NTSC mode Data Sheet Subcarrier Register Value = 32 2 = where: Subcarrier Register Value = d = 2F7CF SD FSC Register : xf SD FSC Register : x7c SD FSC Register 2: xf SD FSC Register 3: x2 Programming the F SC The subcarrier frequency register value is divided into four FSC registers as shown in the previous example. The four subcarrier frequency registers must be updated sequentially, starting with Subcarrier Frequency Register and ending with Subcarrier Frequency Register 3. The subcarrier frequency updates only after the last subcarrier frequency register byte is received by the. The SD input standard autodetection feature must be disabled. Typical F SC Values Table 42 outlines the values that should be written to the subcarrier frequency registers for NTSC and PAL B/D/G/H/I. Table 42.

Using this mode, progressive inputs at twice the frame rate of NTSC and PAL (24p/59.94 Hz and 288p/5 Hz, respectively) can be input into the. The SD noninterlaced mode can be enabled using Subaddress x88, Bit. A 27 MHz clock signal must be provided on the CLKIN_A pin. Embedded EAV/SAV timing codes or external horizontal and vertical synchronization signals provided on the S_HSYNC and S_VSYNC pins can be used to synchronize the input pixel data. All input configurations, output configurations, and features available in NTSC and PAL modes are available in SD noninterlaced mode. For 24p/59.94 Hz input, the ADV7342/ ADV7343 should be configured for NTSC operation, and Subaddress x88, Bit should be set to. For 288p/5 Hz input, the should be configured for PAL operation, and Subaddress x88, Bit should be set to. where the sum is rounded to the nearest integer. Rev. D Page 54 of 8

The active resolution is For PAL operation, an input clock of 29.5 MHz is required. The active resolution is For CVBS and S-Video (Y-C) outputs, the SD subcarrier frequency registers must be updated to reflect the input clock frequency used in SD square pixel mode. The SD input standard autodetection feature must be disabled in SD square pixel mode. In square pixel mode, the timing diagrams shown in Figure 6 and Figure 6 apply.

The PrPb filter supports several different frequency responses, including six low-pass responses, a CIF response, and a QCIF response, as shown in Figure 38 and Figure 39. If SD SSAF gain is enabled (Subaddress x87, Bit 4), there are 3 response options in the 4 db to +4 db range. The desired response can be programmed using Subaddress xa2. The variation in frequency responses is shown in Figure 35 to Figure 37. In addition to the chroma filters listed in Table 43, the ADV7342/ ADV7343 contain an SSAF filter that is specifically designed for the color difference component outputs, Pr and Pb. This filter has a cutoff frequency of ~2.7 MHz and a gain of 4 db at 3.8 MHz (see Figure 62). This filter can be controlled with Subaddress x82, Bit. GAIN (db) FREQUENCY (MHz) Figure 62.

They are not functional as color controls for external pixel data input. The values for the luma (Y) and the color difference (Cr and Cb) signals used to obtain white, black, and saturated primary and complementary colors conform to the ITU-R BT.6-4 standard Table 47. ED/HD Color Space Conversion Options Input Output YPrPb/RGB Out (Subaddress x2, Bit 5) YCrCb YPrPb YCrCb RGB RGB RGB RGB In/YCrCb In (Subaddress x35, Bit ) SD Manual CSC Matrix Adjust Feature The SD manual CSC matrix adjust feature provides custom coefficient manipulation for RGB to YPbPr conversion (for YPbPr to RGB conversion, this matrix adjustment is not available). Normally, there is no need to modify the SD matrix coefficients because the CSC matrix automatically performs the color space conversion based on the output color space selected (see Table 46). Note that Bit 7 in Subaddress x87 must be set to enable RGB input and, therefore, use the CSC manual adjustment. Table 45 shows sample color values that can be programmed into the color registers when the output standard selection is set to EIA 77.2/EIA 77.3 (Subaddress x3, Bits[:] = ). Rev. D Page 57 of 8

58 Data Sheet The SD CSC matrix scalar uses the following equations: Y = (a R) + (a2 G) + (a3 B) + a4 Pr = (b R) + (b2 G) + (b3 B) + b4 Pb = (c R) + (c2 G) + (c3 B) + c4 The coefficients and their default values and register locations are shown in Table 48.

The ED/HD manual CSC matrix adjust feature can be enabled using Subaddress x2, Bit 3. Normally, there is no need to enable this feature because the CSC matrix automatically performs the color space conversion based on the input mode chosen (ED or HD) and the input and output color spaces selected (see Table 47). For this reason, the ED/HD manual CSC matrix adjust feature is disabled by default. If RGB output is selected, the ED/HD CSC matrix scalar uses the following equations: R = GY Y + RV Pr G = GY Y (GU Pb) (GV Pr) B = GY Y + BU Pb Note that subtractions are implemented in hardware. If YPrPb output is selected, the following equations are used: Y = GY Y Pr = RV Pr Pb = BU Pb where: GY = Subaddress x5, Bits[7:] and Subaddress x3, Bits[:]. GU = Subaddress x6, Bits[7:] and Subaddress x4, Bits[7:6]. GV = Subaddress x7, Bits[7:] and Subaddress x4, Bits[5:4]. BU = Subaddress x8, Bits[7:] and Subaddress x4, Bits[3:2]. RV = Subaddress x9, Bits[7:] and Subaddress x4, Bits[:]. On power-up, the CSC matrix is programmed with the default values shown in Table 49. Rev. D Page 58 of 8 Table 49. ED/HD Manual CSC Matrix Default Values Subaddress Default x3 x3 x4 xf x5 x4e x6 xe x7 x24 x8 x92 x9 x7c When the ED/HD manual CSC matrix adjust feature is enabled, the default coefficient values in Subaddress x3 to Subaddress x9 are correct for the HD color space only. The color components are converted according to the following 8i and 72p standards (SMPTE 274M, SMPTE 296M): R = Y +.575Pr G = Y.468Pr.87Pb B = Y +.855Pb The conversion coefficients should be multiplied by 35 before being written to the ED/HD CSC matrix registers This is reflected in the default values for GY = x3b, GU = x3b, GV = x93, BU = x248, and RV = xf. If the ED/HD manual CSC matrix adjust feature is enabled and another input standard (such as ED) is used, the scale values for GY, GU, GV, BU, and RV must be adjusted according to this input standard color space. The user should consider that the color component conversion may use different scale values. For example, SMPTE 293M uses the following conversion: R = Y +.42Pr G = Y.74Pr.344Pb B = Y +.773Pb The programmable CSC matrix is used for external ED/HD pixel data and is not functional when internal test patterns are enabled. Programming the CSC Matrix If custom manipulation of the ED/HD CSC matrix coefficients is required for a YCrCb-to-RGB color space conversion, use the following procedure:. Enable the ED/HD manual CSC matrix adjust feature (Subaddress x2, Bit 3). 2. Set the output to RGB (Subaddress x2, Bit 5). 3. Disable sync on PrPb (Subaddress x35, Bit 2). 4. Enable sync on RGB (optional) (Subaddress x2, Bit 4). The GY value controls the green signal output level, the BU value controls the blue signal output level, and the RV value controls the red signal output level.

59 Data Sheet SD LUMA AND COLOR SCALE CONTROL Subaddress x9c to Subaddress x9f When enabled, the SD luma and color scale control feature can be used to scale the SD Y, Cb, and Cr output levels. This feature can be enabled using Subaddress x87, Bit. This feature affects all SD output signals, that is, CVBS, Y-C, YPrPb, and RGB. When enabled, three -bit registers (SD Y Scale, SD Cb scale, and SD Cr scale) control the scaling of the SD Y, Cb, and Cr output levels. The SD Y scale register contains the scaling factor used to scale the Y level from. to.5 times its initial level. The SD Cb scale and SD Cr scale registers contain the scaling factors to scale the Cb and Cr levels from. to 2. times their initial levels, respectively. The values to be written to these -bit registers are calculated using the following equation: Y, Cb, or Cr Scale Value = Scale Factor 52 For example, if Scale Factor =.3 Y, Cb, or Cr Scale Value =.3 52 = Y, Cb, or Cr Scale Value = 666 (rounded to the nearest integer) Y, Cb, or Cr Scale Value = b Subaddress x9c, SD scale LSB register = x2a Subaddress x9d, SD Y scale register = xa6 Subaddress x9e, SD Cb scale register = xa6 Subaddress x9f, SD Cr scale register = xa6 It is recommended that the SD luma scale saturation feature (Subaddress x87, Bit ) be enabled when scaling the Y output level to avoid excessive Y output levels. SD HUE ADJUST CONTROL Subaddress xa When enabled, the SD hue adjust control register (Subaddress xa) is used to adjust the hue on the SD composite and chroma outputs. This feature can be enabled using Subaddress x87, Bit 2. Subaddress xa contains the bits required to vary the hue of the video data, that is, the variance in phase of the subcarrier during active video with respect to the phase of the subcarrier during the color burst. The provide a range of ±22.5 in increments of For normal operation (zero adjustment), this register is set to x8. Value xff and Value x represent the upper and lower limits, respectively, of the attainable adjustment in NTSC mode. Value xff and Value x represent the upper and lower limits, respectively, of the attainable adjustment in PAL mode. The hue adjust value is calculated using the following equation: Hue Adjust ( ) = (HCRd 28) where HCRd is the hue adjust control register (decimal). For example, to adjust the hue by +4, write x97 to the hue adjust control register d = x where the sum is rounded to the nearest integer. To adjust the hue by 4, write x69 to the hue adjust control register d = x where the sum is rounded to the nearest integer. SD BRIGHTNESS DETECT Subaddress xba The allow monitoring of the brightness level of the incoming video data. This feature is used to monitor the average brightness of the incoming Y signal on a field-byfield basis. The information is read from the I 2 C and, based on this information, the color saturation, contrast, and brightness controls can be adjusted (for example, to compensate for very dark pictures). The luma data is monitored in the active video area only. The average brightness I 2 C register is updated on the falling edge of every VSYNC signal. The SD brightness detect register (Subaddress xba) is a read-only register. SD BRIGHTNESS CONTROL Subaddress xa, Bits[6:] When this feature is enabled, the SD brightness/wss control register (Subaddress xa) is used to control brightness by adding a programmable setup level onto the scaled Y data. This feature can be enabled using Subaddress x87, Bit 3. For NTSC with pedestal, the setup can vary from IRE to 22.5 IRE. For NTSC without pedestal and for PAL, the setup can vary from 7.5 IRE to +5 IRE. The SD brightness control register is an 8-bit register. The seven LSBs of this 8-bit register are used to control the brightness level, which can be a positive or negative value. For example, to add a +2 IRE brightness level to an NTSC signal with pedestal, write x28 to Subaddress xa. (SD Brightness Value) = (IRE Value 2.563) = ( ) = (4.3262) x28 Rev. D Page 59 of 8

SD INPUT STANDARD AUTODETECTION Subaddress x87, Bit 5 The include an SD input standard autodetect feature. This SD feature can be enabled by setting Subaddress x87, Bits[5:]. When enabled, the can automatically identify an NTSC or a PAL B/D/G/H/I input stream. The automatically update the subcarrier frequency registers with the appropriate value for the identified standard. The are also configured to correctly encode the identified standard.

61 Data Sheet DOUBLE BUFFERING Subaddress x33, Bit 7 for ED/HD; Subaddress x88, Bit 2 for SD Double-buffered registers are updated once per field. Double buffering improves overall performance because modifications to register settings are not made during active video but take effect prior to the start of the active video on the next field. Double buffering can be activated on the following ED/HD registers using Subaddress x33, Bit 7: the ED/HD Gamma A and Gamma B curves and ED/HD CGMS registers. Double buffering can be activated on the following SD registers using Subaddress x88, Bit 2: the SD Gamma A and Gamma B curves, SD Y scale, SD Cr scale, SD Cb scale, SD brightness, SD closed captioning, and SD Macrovision Bits[5:] (Subaddress xe, Bits[5:]) registers. PROGRAMMABLE DAC GAIN CONTROL Subaddress xa to Subaddress xb It is possible to adjust the DAC output signal gain up or down from its absolute level. This is illustrated in Figure 66. DAC 4 to DAC 6 are controlled by Register xa. DAC to DAC 3 are controlled by Register xb. CASE A GAIN PROGRAMMED IN DAC OUTPUT LEVEL REGISTERS, SUBADDRESS xa, xb 7mV 3mV In Case B of Figure 66, the video output signal is reduced. The absolute level of the sync tip and the blanking level decrease with respect to the reference video output signal. The overall gain of the signal is reduced from the reference signal. The range of this feature is specified for ±7.5% of the nominal output from the DACs. For example, if the output current of the DAC is 4.33 ma, the DAC gain control feature can change this output current from 4.8 ma ( 7.5%) to ma (+7.5%). The reset value of the control registers is x; that is, nominal DAC current is output. Table 5 shows how the output current of the DACs varies for a nominal 4.33 ma output current. Table 5.

It can also be applied wherever nonlinear processing is used. Gamma correction uses the function 3mV Figure 66. Programmable DAC Gain Positive and Negative Gain In Case A of Figure 66, the video output signal is gained. The absolute level of the sync tip and the blanking level increase with respect to the reference video output signal. The overall gain of the signal is increased from the reference signal SignalOUT = (SignalIN) γ where γ is the gamma correction factor. Gamma correction is available for SD and ED/HD video. For both variations, there are twenty 8-bit registers. They are used to program the Gamma Correction Curve A and Gamma Correction Curve B. ED/HD gamma correction is enabled using Subaddress x35, Bit 5. ED/HD Gamma Correction Curve A is programmed at Subaddress x44 to Subaddress x4d, and ED/HD Gamma Correction Curve B is programmed at Subaddress x4e to Subaddress x57. Rev. D Page 6 of 8

62 SD gamma correction is enabled using Subaddress x88, Bit 6. SD Gamma Correction Curve A is programmed at Subaddress xa6 to Subaddress xaf, and SD Gamma Correction Curve B is programmed at Subaddress xb to Subaddress xb9. Gamma correction is performed on the luma data only. The user can choose one of two correction curves, Curve A or Curve B. Only one of these curves can be used at a time. For ED/HD gamma correction, curve selection is controlled using Subaddress x35, Bit 4. For SD gamma correction, curve selection is controlled using Subaddress x88, Bit 7. The shape of the gamma correction curve is controlled by defining the curve response at different locations along the curve. By altering the response at these locations, the shape of the gamma correction curve can be modified. Between these points, linear interpolation is used to generate intermediate values. Considering that the curve has a total length of 256 points, the programmable locations are at the following points: 24, 32, 48, 64, 8, 96, 28, 6, 92, and 224. The following locations are fixed and cannot be changed:, 6, 24, and 255. From the curve locations, 6 to 24, the values at the programmable locations and, therefore, the response of the gamma correction curve, should be calculated to produce the following result: xdesired = (xinput) γ where: xdesired is the desired gamma corrected output. xinput is the linear input signal. γ is the gamma correction factor. Data Sheet To program the gamma correction registers, calculate the programmable curve values using the following formula: γ 6 n γ (24 6) n = where: γn is the value to be written into the gamma correction register for point n on the gamma correction curve. n = 24, 32, 48, 64, 8, 96, 28, 6, 92, or 224. γ is the gamma correction factor. For example, setting γ =.5 for all programmable curve data points results in the following yn values: y24 = [(8/224).5 224] + 6 = 58 y32 = [(6/224).5 224] + 6 = 76 y48 = [(32/224).5 224] + 6 = y64 = [(48/224).5 224] + 6 = 2 y8 = [(64/224).5 224] + 6 = 36 y96 = [(8/224).5 224] + 6 = 5 y28 = [(2/224).5 224] + 6 = 74 y6 = [(44/224).5 224] + 6 = 95 y92 = [(76/224).5 224] + 6 = 24 y224 = [(28/224).5 224] + 6 = 232 where the sum of each equation is rounded to the nearest integer. The gamma curves in Figure 67 and Figure 68 are examples only; any user-defined curve in the range from 6 to 24 is acceptable. 3 GAMMA CORRECTION BLOCK OUTPUT TO A RAMP INPUT 3 GAMMA CORRECTION BLOCK TO A RAMP INPUT FOR VARIOUS GAMMA VALUES GAMMA CORRECTED AMPLITUDE SIGNAL INPUT SIGNAL OUTPUT GAMMA CORRECTED AMPLITUDE SIGNAL INPUT LOCATION Figure 67.

63 Data Sheet ED/HD SHARPNESS FILTER AND ADAPTIVE FILTER CONTROLS Subaddress x4; Subaddress x58 to Subaddress x5d There are three filter modes available on the : a sharpness filter mode and two adaptive filter modes. ED/HD Sharpness Filter Mode To enhance or attenuate the Y signal in the frequency ranges shown in Figure 69, the ED/HD sharpness filter must be enabled (Subaddress x3, Bit 7) and the ED/HD adaptive filter must be disabled (Subaddress x35, Bit 7). To select one of the 256 individual responses, the corresponding gain values, which range from 8 to +7 for each filter, must be programmed into the ED/HD sharpness filter gain register at Subaddress x4. ED/HD Adaptive Filter Mode The ED/HD adaptive filter (Threshold A, Threshold B, and Threshold C) registers, the ED/HD adaptive filter (Gain, Gain 2, and Gain 3) registers, and the ED/HD sharpness filter gain register are used in adaptive filter mode. To activate the adaptive filter control, the ED/HD sharpness filter and the ED/HD adaptive filter must be enabled (Subaddress x3, Bit 7, and Subaddress x35, Bit 7, respectively). The derivative of the incoming signal is compared to the three programmable threshold values: ED/HD adaptive filter (Threshold A, Threshold B, and Threshold C) registers (Subaddress x5b, Subaddress x5c, and Subaddress x5d, respectively). The recommended threshold range is 6 to 235, although any value in the range of to 255 can be used. The edges can then be attenuated with the settings in the ED/HD adaptive filter (Gain, Gain 2, and Gain 3) registers (Subaddress x58, Subaddress x59, and Subaddress x5a, respectively), and the ED/HD sharpness filter gain register (Subaddress x4). There are two adaptive filter modes available. The mode is selected using the ED/HD adaptive filter mode control (Subaddress x35, Bit 6) as follows: Mode A is used when the ED/HD adaptive filter mode control is set to. In this case, Filter B (LPF) is used in the adaptive filter block. In addition, only the programmed values for Gain B in the ED/HD sharpness filter gain register and ED/HD adaptive filter (Gain, Gain 2, and Gain 3) registers are applied when needed. The Gain A values are fixed and cannot be changed. Mode B is used when ED/HD adaptive filter mode control is set to. In this mode, a cascade of Filter A and Filter B is used. Both settings for Gain A and Gain B in the ED/HD sharpness filter gain register and ED/HD adaptive filter (Gain, Gain 2, and Gain 3) registers become active when needed.

Output Signal from ED/HD Adaptive Filter (Mode B) SD DIGITAL NOISE REDUCTION Subaddress xa3 to Subaddress xa5 Digital noise reduction (DNR) is applied to the Y data only. A filter block selects the high frequency, low amplitude components of the incoming signal (DNR input select). The absolute value of the filter output is compared to a programmable threshold value (DNR threshold control). There are two DNR modes available: DNR mode and DNR sharpness mode. In DNR mode, if the absolute value of the filter output is smaller than the threshold, it is assumed to be noise. A programmable amount (coring gain border, coring gain data) of this noise signal is subtracted from the original signal. In DNR sharpness mode, if the absolute value of the filter output is less than the programmed threshold, it is assumed to be noise. Otherwise, if the level exceeds the threshold, now identified as a valid signal, a fraction of the signal (coring gain border, coring gain data) is added to the original signal to boost high frequency components and sharpen the video image. In MPEG systems, it is common to process the video information in blocks of 8 pixels 8 pixels for MPEG2 systems or 6 pixels 6 pixels for MPEG systems (block size control). DNR can be applied to the resulting block transition areas that are known to contain noise. Generally, the block transition area contains two pixels. It is possible to define this area to contain four pixels (border area). It is also possible to compensate for variable block positioning or differences in YCrCb pixel timing with the use of the DNR block offset. The digital noise reduction registers are three 8-bit registers. They are used to control the DNR processing Y DATA INPUT DNR SHARPNESS MODE NOISE SIGNAL PATH INPUT FILTER BLOCK DNR CONTROL BLOCK SIZE CONTROL BORDER AREA BLOCK OFFSET GAIN CORING GAIN DATA CORING GAIN BORDER FILTER OUTPUT > THRESHOLD?

If this bit is set to Logic, the border transition area consists of two pixels, where one pixel refers to two clock cycles at 27 MHz PIXELS (NTSC) 8 8 PIXEL BLOCK TWO-PIXEL BORDER DATA Figure 76. SD DNR Border Area 8 8 PIXEL BLOCK Block Size Control Subaddress xa4, Bit 7 This bit is used to select the size of the data blocks to be processed. Setting the block size control function to Logic defines a 6 pixel 6 pixel data block, and Logic defines an 8 pixel 8 pixel data block, where one pixel refers to two clock cycles at 27 MHz. MAGNITUDE FILTER D FILTER C FILTER B DNR Input Select Control Subaddress xa5, Bits[2:] Three bits are assigned to select the filter, which is applied to the incoming Y data. The signal that lies in the pass band of the selected filter is the signal that is DNR processed. Figure 77 shows the filter responses selectable with this control. DNR Mode Control Subaddress xa5, Bit 3 This bit controls the DNR mode selected. Logic selects DNR mode; Logic selects DNR sharpness mode. DNR works on the principle of defining low amplitude, high frequency signals as probable noise and subtracting this noise from the original signal. In DNR mode, it is possible to subtract a fraction of the signal that lies below the set threshold, assumed to be noise, from the original signal. The threshold is set in DNR Register. When DNR sharpness mode is enabled, it is possible to add a fraction of the signal that lies above the set threshold to the original signal because this data is assumed to be valid data and not noise. The overall effect is that the signal is boosted (similar to using the extended SSAF filter). DNR Block Offset Control Subaddress xa5, Bits[7:4] Four bits are assigned to this control, which allows a shift of the data block of 5 pixels maximum. Consider the coring gain positions fixed. The block offset shifts the data in steps of one pixel such that the border coring gain factors can be applied at the same position regardless of variations in input timing of the data. SD ACTIVE VIDEO EDGE CONTROL Subaddress x82, Bit 7 The are able to control fast rising and falling signals at the start and end of active video in order to minimize ringing. When the active video edge control feature is enabled (Subaddress x82, Bit 7 = ), the first three pixels and the last three pixels of the active video on the luma channel are scaled so that maximum transitions on these pixels are not possible. At the start of active video, the first three pixels are multiplied by /8, /2, and 7/8, respectively. Approaching the end of active video, the last three pixels are multiplied by 7/8, /2, and /8, respectively. All other active video pixels pass through unprocessed..2 FILTER A FREQUENCY (MHz) Figure 77. SD DNR Input Select Rev. D Page 66 of 8

To use this low power mode, these DACs must be operating in full-drive mode (RSET = 5 Ω, RL = 37.5 Ω). Low power mode is not available in lowdrive mode (RSET = 4.2 kω, RL = 3 Ω). Low power mode can be independently enabled or disabled on DAC, DAC 2, and DAC 3 using Subaddress xd, Bits[2:]. Low power mode is disabled by default on each DAC. In low power mode, DAC current consumption is content dependent. On a typical video stream, it can be reduced by as much as 4%. For applications requiring the highest possible video performance, low power mode should be disabled. CABLE DETECTION Subaddress x The include an Analog Devices proprietary cable detection feature. The cable detection feature is available on DAC and DAC 2, while operating in full-drive mode (RSET = 5 Ω, RL = 37.5 Ω, assuming a connected cable). The feature is not available in low-drive mode (RSET = 4.2 kω, RL = 3 Ω). For a DAC to be monitored, the DAC must be powered up in Subaddress x. The cable detection feature can be used with all SD, ED, and HD video standards. It is available for all output configurations, that is, CVBS, YC, YPrPb, and RGB output configurations. For CVBS/YC output configurations, both DAC and DAC 2 are monitored; that is, the CVBS and YC luma outputs are monitored. For YPrPb and RGB output configurations, only Vertical blanking interval Aligned with serration lines Vertical blanking interval In all ED/HD standards where there is a VSYNC output, the start of the VSYNC pulse is aligned with the falling edge of the embedded VSYNC in the output video. 2 X = don t care. DAC is monitored; that is, the luma or green output is monitored. Once per frame, the monitor DAC and/or DAC 2, updating Subaddress x, Bit and Bit, respectively. If a cable is detected on one of the DACs, the relevant bit is set to. If not, the bit is set to. DAC AUTOPOWER-DOWN Subaddress x, Bit 4 For power-sensitive applications, a DAC autopower-down feature can be enabled using Subaddress x, Bit 4. This feature is available only when the cable detection feature is enabled. With this feature enabled, the cable detection circuitry monitors DAC and/or DAC 2 once per frame. If they are unconnected, some or all of the DACs automatically power down. Which DAC or DACs are powered down depends on the selected output configuration. For CVBS/YC output configurations, if DAC is unconnected, only DAC powers down. If DAC 2 is unconnected, DAC 2 and DAC 3 power down. For YPrPb and RGB output configurations, if DAC is unconnected, all three DACs power down. DAC 2 is not monitored for YPrPb and RGB output configurations. Once per frame, DAC and/or DAC 2 is monitored. If a cable is detected, the appropriate DAC or DACs remain powered up for the duration of the frame. If no cable is detected, the appropriate DAC or DACs power down until the next frame, when the process is repeated.

70 SLEEP MODE Subaddress x, Bit In sleep mode, most of the digital I/O pins of the ADV7342/ ADV7343 are disabled. For inputs, this means that the external data is ignored, and internally the logic normally driven by a given input is just tied low or high. This includes CLKINx. For digital output pins, this means that the pin goes into tristate (high impedance) mode. There are some exceptions to allow the user to continue to communicate with the part via I 2 C: the ALSB, SDA, and SCL pins are kept alive. PIXEL AND CONTROL PORT READBACK Subaddress x2 to Subaddress x4, Subaddress x6 The support the readback of most digital inputs via the I 2 C MPU port. This feature is useful for board level connectivity testing with upstream devices. The pixel port (S[7:], Y[7:], and C[7:]), the control port (S_HSYNC, S_VSYNC, P_HSYNC, P_VSYNC, and P_BLANK), and the SFL pin are available for readback via the MPU port. The readback registers are located at Subaddress x2 to Subaddress x4 and Subaddress x6. When using this feature, apply a clock signal to the CLKIN_A pin to register the levels applied to the input pins. RESET MECHANISM Subaddress x7, Bit The have a software reset accessible via the I 2 C MPU port. A software reset is activated by writing a to Subaddress x7, Bit. This resets all registers to their default values. This bit is self-clearing; that is, after a has been written to the bit, the bit automatically returns to. Data Sheet The include a power-on reset (POR) circuit to ensure correct operation after power-up. SD TELETEXT INSERTION Subaddress xc9 to Subaddress xce The support the insertion of teletext data, using a 2-pin interface, when operating in PAL mode. Teletext insertion is enabled using Subaddress xc9, Bit. In accordance with the PAL WST teletext standard, teletext data should be inserted into the at a rate of Mbps. The teletext data can be inserted on the S_VSYNC, P_VSYNC, or C pin. The pin on which the teletext data is inserted is selected using Subaddress xc9, Bits [3:2]. When teletext insertion is enabled, a teletext request signal is output from the to indicate when teletext data should be inserted. The teletext request signal is output on the SFL pin. The position (relative to the teletext data) and width of the request signal are configurable using Subaddress xca. The request signal can operate in either a line or a bit mode. The request signal mode is controlled using Subaddress xc9, Bit. To account for the noninteger relationship between the teletext insertion rate ( Mbps) and the pixel clock (27 MHz), a teletext insertion protocol is implemented in the ADV7342/ ADV7343. At a rate of Mbps, the time taken for the insertion of 37 teletext bits equates to 44 pixel clock cycles (at 27 MHz). For every 37 teletext bits inserted into the ADV7342/ ADV7343, the th, 9 th, 28 th, and 37 th bits are carried for three pixel clock cycles, and the remainder are carried for four pixel clock cycles (totaling 44 pixel clock cycles). The teletext insertion protocol repeats every 37 teletext bits or 44 pixel clock cycles until all 36 teletext bits are inserted. 45 BYTES (36 BITS) PAL TELETEXT VBI LINE ADDRESS AND DATA RUN-IN CLOCK Figure 8.

72 Data Sheet PRINTED CIRCUIT BOARD LAYOUT AND DESIGN UNUSED PINS If the S_HSYNC, S_VSYNC, P_HSYNC, and P_VSYNC pins are not used, they should be tied to VDD_IO through a pull-up resistor ( kω or 4.7 kω). Any other unused digital inputs should be tied to ground. Unused digital output pins should be left floating. DAC outputs can be either left floating or connected to GND. Disabling these outputs is recommended. DAC CONFIGURATIONS The contain six DACs. All six DACs can be configured to operate in low-drive mode. Low-drive mode is defined as 4.33 ma full-scale current into a 3 Ω load, RL. DAC, DAC 2, and DAC 3 can also be configured to operate in full-drive mode. Full-drive mode is defined as 34.7 ma fullscale current into a 37.5 Ω load, RL. Full-drive is the recommended mode of operation for DAC, DAC 2, and DAC 3. The contain two RSET pins. A resistor connected between the RSET pin and AGND is used to control the full-scale output current and, therefore, the DAC output voltage levels of DAC, DAC 2, and DAC 3. For low-drive operation, RSET must have a value of 4.2 kω, and RL must have a value of 3 Ω. For full-drive operation, RSET must have a value of 5 Ω, and RL must have a value of 37.5 Ω. A resistor connected between the RSET2 pin and AGND is used to control the full-scale output current and, therefore, the DAC output voltage levels of DAC 4, DAC 5, and DAC 6. RSET2 must have a value of 4.2 kω, and RL must have a value of 3 Ω (that is, low-drive operation only). The resistors connected to the RSET and RSET2 pins should have a % tolerance. The contain two compensation pins, COMP and COMP2. A 2.2 nf compensation capacitor should be connected from each of these pins to VAA. VOLTAGE REFERENCE The contain an on-chip voltage reference that can be used as a board-level voltage reference via the VREF pin. Alternatively, the can be used with an external voltage reference by connecting the reference source to the VREF pin. For optimal performance, use an external voltage reference such as the AD58 with the ADV7342/ ADV7343. If an external voltage reference is not used, a. µf capacitor should be connected from the VREF pin to VAA. VIDEO OUTPUT BUFFER AND OPTIONAL OUTPUT FILTER An output buffer is necessary on any DAC that operates in lowdrive mode (RSETx = 4.2 kω, RL = 3 Ω). Analog Devices produces a range of op amps suitable for this application, for example, the AD86. For more information about line driver buffering circuits, see the relevant op amp data sheet. An optional reconstruction (anti-imaging) low-pass filter (LPF) may be required on the DAC outputs if the are connected to a device that requires this filtering. The filter specifications vary with the application. The use of 6 (SD), 8 (ED), or 4 (HD) oversampling can remove the requirement for a reconstruction filter altogether. For applications requiring an output buffer and reconstruction filter, the ADA443-, ADA44-3, and ADA44-6 integrated video filter buffers should be considered. Table 58.

Output Filter Plot for HD, 4 Oversampling PRINTED CIRCUIT BOARD (PCB) LAYOUT The are highly integrated circuits containing both precision analog and high speed digital circuitry. They are designed to minimize interference effects on the integrity of the analog circuitry by the high speed digital circuitry. It is imperative that these same design and layout techniques be applied to the system-level design so that optimal performance is achieved. The layout should be optimized for lowest noise on the power and ground planes by shielding the digital inputs and providing good power supply decoupling. It is recommended to use a 4-layer printed circuit board with ground and power planes separating the signal trace layer and the solder side layer. Component Placement Component placement should be carefully considered to separate noisy circuits, such as clock signals and high speed digital circuitry, from analog circuitry. The external loop filter components and components connected to the COMP, V REF, and RSETx pins should be placed as close as possible to and on the same side of the PCB as the ADV7342/ ADV7343. Adding vias to the PCB to get the components closer to the is not recommended. It is recommended that the be placed as close as possible to the output connector, with the DAC output traces as short as possible. The termination resistors on the DAC output traces should be placed as close as possible to and on the same side of the PCB as the. The termination resistors should overlay the PCB ground plane. PHASE (Degrees) Rev. D Page 73 of 8

74 External filter and buffer components connected to the DAC outputs should be placed as close as possible to the ADV7342/ ADV7343 to minimize the possibility of noise pickup from neighboring circuitry and to minimize the effect of trace capacitance on output bandwidth. This is particularly important when operating in low-drive mode (RSETx = 4.2 kω, RL = 3 Ω). Power Supplies It is recommended that a separate regulated supply be provided for each power domain (VAA, VDD, VDD_IO, and PVDD). For optimal performance, linear regulators rather than switch mode regulators should be used. If switch mode regulators must be used, care must be taken with regard to the quality of the output voltage in terms of ripple and noise. This is particularly true for the VAA and PVDD power domains. Each power supply should be individually connected to the system power supply at a single point through a suitable filtering device, such as a ferrite bead. Power Supply Decoupling It is recommended that each power supply pin be decoupled with nf and. µf ceramic capacitors. The VAA, PVDD, VDD_IO, and both VDD pins should be individually decoupled to ground. The decoupling capacitors should be placed as close as possible to the with the capacitor leads kept as short as possible to minimize lead inductance. A µf tantalum capacitor is recommended across the VAA supply in addition to the nf and. µf ceramic capacitors. Power Supply Sequencing If the ALSB pin is tied low, a power supply sequence is required for proper operation of the part. The VDD_IO power supply must Data Sheet be established a minimum of 25 µs prior to the VDD power supply being established. The VAA and PVDD power supplies can be established at any time and in any order. Tying ALSB to VDD_IO completely removes this PSS requirement. Digital Signal Interconnect The digital signal traces should be isolated as much as possible from the analog outputs and other analog circuitry. Digital signal traces should not overlay the VAA or PVDD power plane. Due to the high clock rates used, avoid long clock traces to the to minimize noise pickup. Any pull-up termination resistors for the digital inputs should be connected to the VDD_IO power supply. Any unused digital inputs should be tied to ground. Analog Signal Interconnect DAC output traces should be treated as transmission lines with appropriate measures taken to ensure optimal performance (for example, impedance matched traces). The DAC output traces should be kept as short as possible. The termination resistors on the DAC output traces should be placed as close as possible to, and on the same side of the PCB as, the. To avoid crosstalk between the DAC outputs, it is recommended that as much space as possible be left between the traces connected to the DAC output pins. Adding ground traces between the DAC output traces is also recommended. Rev. D Page 74 of 8

80 SD CLOSED CAPTIONING Subaddress x9 to Subaddress x94 The support closed captioning conforming to the standard television synchronizing waveform for color transmission. Closed captioning is transmitted during the blanked active line time of Line 2 of the odd fields and Line 284 of the even fields. Closed captioning consists of a seven-cycle sinusoidal burst that is frequency- and phase-locked to the caption data. After the clock run-in signal, the blanking level is held for two data bits and is followed by the Logic start bit. Sixteen bits of data follow the start bit. These consist of two 8-bit bytes, seven data bits, and one odd parity bit. The data for these bytes is stored in the SD closed captioning registers (Subaddress x93 to Subaddress x94). The also support the extended closed captioning operation, which is active during even fields and encoded on scan Line 284. The data for this operation is stored in the SD closed captioning registers (Subaddress x9 to Subaddress x92). The automatically generate all clock runin signals and timing that support closed captioning on Line 2 Data Sheet and Line 284. All pixels inputs are ignored on Line 2 and on Line 284 if closed captioning is enabled. The FCC Code of Federal Regulations (CFR) 47 Section 5.9 and EIA-68 describe the closed captioning information for Line 2 and Line 284. The use a single buffering method. This means that the closed captioning buffer is only -byte deep. Therefore, there is no frame delay in outputting the closed captioning data, unlike other 2-byte deep buffering systems. The data must be loaded one line before it is output on Line 2 and Line 284. A typical implementation of this method is to use VSYNC to interrupt a microprocessor, which in turn loads the new data (two bytes) in every field. If no new data is required for transmission, s must be inserted in both data registers; this is called nulling. It is also important to load control codes, all of which are double bytes, on Line 2. Otherwise, a TV does not recognize them. If there is a message such as Hello World that has an odd number of characters, it is important to add a blank character at the end to make sure that the end-of-caption, 2-byte control code lands in the same field..5 ±.25µs 2.9µs 7 CYCLES OF.535MHz CLOCK RUN-IN TWO 7-BIT + PARITY ASCII CHARACTERS (DATA) 5 IRE S T A R T D TO D6 P A R I T Y D TO D6 P A R I T Y 4 IRE REFERENCE COLOR BURST (9 CYCLES) FREQUENCY = F SC = MHz AMPLITUDE = 4 IRE.3µs µs BYTE µs BYTE Figure 98.

81 Data Sheet INTERNAL TEST PATTERN GENERATION SD TEST PATTERNS The are able to internally generate SD color bar and black bar test patterns. For this function, a 27 MHz clock signal must be applied to the CLKIN_A pin. The register settings in Table 6 are used to generate an SD NTSC 75% color bar test pattern. CVBS output is available on DAC 4, S-Video (Y-C) output is on DAC 5 and DAC 6, and YPrPb output is on DAC to DAC 3. On power-up, the subcarrier frequency registers default to the appropriate values for NTSC. All other registers are set as normal/default. Table 6. SD NTSC Color Bar Test Pattern Register Writes Subaddress Setting x xfc x82 xc9 x84 x4 To generate an SD NTSC black bar test pattern, the settings shown in Table 6 should be used with an additional write of x24 to Subaddress x2. For PAL output of either test pattern, the same settings are used, except that Subaddress x8 is programmed to x, and the subcarrier frequency registers are programmed as shown in Table 62. Table 62. PAL FSC Register Writes Subaddress Description Setting x8c FSC xcb x8d FSC x8a x8e FSC2 x9 x8f FSC3 x2a Note that, when programming the FSC registers, the user must write the values in the sequence FSC, FSC, FSC2, FSC3. The full FSC value to be written is accepted only after the FSC3 write is complete. ED/HD TEST PATTERNS The are able to internally generate ED/HD black bar and hatch test patterns. For ED test patterns, a 27 MHz clock signal must be applied to the CLKIN_A pin. For HD test patterns, a MHz clock signal must be applied to the CLKIN_A pin. The register settings in Table 63 are used to generate an ED 525p hatch test pattern. YPrPb output is available on DAC to DAC 3. All other registers are set as normal/default. Table 63. ED 525p Hatch Test Pattern Register Writes Subaddress Setting x xc x x x3 x5 To generate an ED 525p black bar test pattern, the settings shown in Table 63 should be used with an additional write of x24 to Subaddress x2. To generate an ED 525p flat field test pattern, the settings shown in Table 63 should be used, except that xd should be written to Subaddress x3. The Y, Cr, and Cb levels for the hatch and flat field test patterns can be controlled using Subaddress x36, Subaddress x37, and Subaddress x38, respectively. For ED/HD standards other than 525p, the settings shown in Table 63 (and subsequent comments) are used, except that Subaddress x3, Bits[7:3] are updated as appropriate. Rev. D Page 8 of 8
