4 1. Document History Revision Issue Date Reason CN# Rev A Initial release (Europe rev 1.0) Introduction The 2XC20XW-DIG is a CMOS based camera family with an analog and digital output (CCIR656 based). The dimensions are 32*32mm with 4 mounting holes Communication is possible via an OSD keyboard and via software (USB version only). The digital output has been described fully in this document. The camera must be connected via the 30-pin board-to-board connector. This 30-pin board-to-board connector can be used to piggy-back to an application interface circuit board. Examples of application PCB s are: USB 2.0 Board: Videology product that has small dimensions (22x26mm) but can be fixed by screws in holes of the heat sink. When two boards are stacked together a complete USB 2.0 camera is available. Interface to the 60SVMx, Videology s Ethernet server board SDI interface (not available yet) This document is written to give technical background on this camera module, also all the connectors are being described in this application note.

The Digital Output Format The 8-bit data format is shown in the figure below: Y0 V0 Y1 U0 Y2 V1 YUV multiplexed 8- bit Data clock CCIR656 format Note that the camera can offer two additional bits (lower). So the total data has is 10 bits wide. See also the connector pin out.

The first three bytes are always the same. The sequence is [0xFF], [0x00] and [0x00]. The values 0xFF and 0x00 will not occur in the normal video. The fourth byte gives the synchronization position. It makes use of 3 different signals: FIELD, VD and HD. The last 4 bits contain a protection code to check if an error occurred during the transfer of this position code s byte.

8 Horizontal and Vertical Synchronization The camera has two independent synchronization signals in the digital format. One sync signal is HREF. HREF is a negative oriented pulse, which means that the pulse is low during the horizontal blanking period. Note that during the vertical blanking the HREF signal is low. The other sync signal is VREF. VREF is a positive oriented pulse, which means that it is high during the vertical blanking period. VREF also indicates the vertical period when video is not active. = blank H pixels * 1/(0.5 f data clock) t line = act+blank H pixels * 1/(0.5 f data clock) HREF signal VREF t ver.blank = t line *(numb blank lines) t vertical = t line *( numb act lines + numb blank lines) HREF Revision: A Page 8 of 11

9 7. Connectors and Pinning The camera has a 13pin cable connector (J1) and board to board connector (J9) to make digital interconnections as easy as possible.
