VIDEO CONNECTIONS

Connect a source of component digital 525 or 625 line 270 Mb/s video to the BNC labeled SDI INPUT.
Analog video output is available on the ANALOG OUTPUT BNCs. Two SDI outputs are also available
through the SDI OUTPUT BNCs.
2.2.

GENLOCK REFERENCE

For proper synchronization of the output video, the 7735AVC-LB must be locked to a stable 1 volt p-p
composite analog colour black source, applied to the GENLOCK video loop. The internal sync separator
has a high impedance input tapped off the loop through, therefore, the video signal must be properly
terminated at the end of the line.
If Genlock video is not present, the input video is used to determine the output
timing. When the Genlock video is applied or removed, the output video timing will
suddenly jump to the new timing phrase, creating video and audio artifacts.
2.3.

AUDIO AND AUX I/O

The audio outputs are available on a female high density DB-15 connector labeled "Audio and Aux I/O."
Table 2-1 shows the pin-out of the connector:
