1 For Video Equipment MNS External Synchronization Control LSI for Color Video Cameras Overview The MNS is an external synchronization control LSI for color video cameras. When used in combination with a synchronizing signal generator (MN0NS or MN0PS), it provides external synchronization control for NTSC and PAL video systems. Features Synchronization of both the video camera and the VCR External synchronization inputs: Composite synchronizing signal and burst subcarrier External synchronization techniques Horizontal synchronization: phase-locked loop Vertical synchronization: reset technique Subcarrier synchronization: phase-locked loop Support for both NTSC and PAL systems Built-in feature for automatically switching between external and internal synchronization Built-in horizontal phase adjustment circuit Applications Color video cameras Pin Assignment SCPSW SCPSW N/P BGP GLBSC V SS V DD GLSYNC TEST f HP HPCO Xf H OSCI Xf H OSCO 0 (TOP VIEW) SOP0-P-0 0 f SC f SC OSCO f SC OSCI SOPCO V DD V SS TEST HBLK EXT/INT LSWCONT LSW VR Xf H SDB000BEM

For an NTSC system, keep this pin at "H" level. "H" level selects NTSC operation; "L" level, PAL operation. This pin is at "L" level when the signal, after passing through the monostable multivibrator, leads the rising edge of the HSYNC signal derived by separating off the horizontal component of the GLSYNC signal and is at "H" level when the signal lags. At all other times, it is in the high-impedance state. Clock oscillator pins for the synchronization circuits. Connect these pins to an inductor, capacitor, and variable capacitor. (The pins have built-in feedback resistors.) The circuit oscillates during external synchronization mode. The oscillation stops for internal synchronization mode. The oscillator frequency, Xf H is. MHz (0f H ) for NTSC and.0 MHz (f H ) for PAL. Clock output pin for synchronizing signal circuits. This pin provides the clock (Xf H ) for the external synchronization mode and stays at "L" level for the internal synchronization mode. Connect to the EX0f H I pin of the synchronizing signal generator for NTSC operation and to the EXf H I pin for PAL operation.

During internal synchronization mode, this pin remains at "L" level. Connect this pin to the LSWCONT pin on the synchronizing signal generator. If the chip detects GLSYNC input, it switches to external synchronization mode and drives this pin at "H" level. Otherwise, it switches to internal synchronization mode and drives this pin at "L" level. Connect this pin to the EXT/INT pin on the synchronizing signal generator. These pulses have a width of. µs (NTSC) or. µs (PAL) and trail the rising edge of the HSYNC signal by. µs (NTSC) or. µs. They are generated for only 0 H to H (NTSC) or 0 H (PAL) after the VR pulse. These pulses have a width of. µs (NTSC) or. µs (PAL) and follow the rising edge of the HSYNC signal. Leave these test inputs open. (The pins include built-in pull-up resistors.)

5 For Video Equipment MNS Timing Chart. Horizontal synchronization block This block compares the phases of the HSYNC signal derived by separating off the horizontal component of the GLSYNC input and the signal from the synchronizing signal generator after it has passed through the monostable multivibrator. It is thus possible to adjust the horizontal phase by adjusting the CR integral circuit's time constant. GLSYNC HSYNC DELAY Timing chart for horizontal pulse phase comparison. Vertical synchronization block This block detects the V-SERATION interval in the GLSYNC input and generates a vertical reset (VR) pulse with 0. H of the start of that interval. It then issues no pulses for H (NTSC) or 0 H (PAL) after this VR pulse. GLSYNC VR.0µs (NTSC).µs (PAL).µs (NTSC).µs (PAL) Vertical reset pulse timing chart

6 MNS For Video Equipment. Subcarrier synchronization block This block converts the output from the synchronizing signal generator into four signals with the same frequency as the burst subcarrier, but different phases. In this phase-locked loop circuit, the phase of GLBSC is compared with the phase selected by bits (SCPSW and SCPSW). During PAL operation, if the LSW polarity is wrong, this block sends an error detection pulse (LSWCONT) to the synchronizing signal generator and reverses the LSW polarity. It also adjusts the relationship between fields through.. Oscillator blocks The Xf H and f SC oscillator blocks operate only during external synchronization mode. Connecting a variable capacitor creates voltage-controlled oscillators that generate the synchronization signal circuit clock (Xf H ) and subcarrier circuit clock (f SC ) for output to the synchronization signal generator.. Automatic internal/external switching block If it detects a minimum of ten edges from the GLSYNC input, this block switches the chip to the external synchronization mode and drives the EXT/INT pin at "H" level. If there are no edges in the GLSYNC input for 0 H, this block switches the chip to the internal synchronization mode and drives this pin at "L" level.
