How do I set up the ADV7802?

Dave, Joe,

 

I have 2 open questions about the ADV7802;

 

1. I turned on the TBC and that cleans up the jitter, but it also messes up the equalization. Should it change the video settings? Or should I triple check the SW engineer's code to see if other registers have been changed?

 

2. We accidentally put a 82 nF cap in series with the 160 ohm resistor on ELPF2. With the 82 nF cap the jiitter (after our de-jitter) is steady at

0.16 or 0.17 UI but if I use the recommended 820 nF cap the jitter doubles (0.30-0.34).

How much jitter should I expect with the 820 nF cap?

 

Thanks for the help.

 

Wayne
