ADV7619 297MHz stability issue

Hello everyone,

 

I am using the ADV7619 on a production board to acquire several video standards, but it seems that standards running at high frequency clock are (sometimes) not sampled correctly. I get jitter in the output frame.

 

For now, I am using the last scripts (ADV7619-VER.1.9c.zip).

 

- Do you think it could be due to electrical issue? Is there some external component values that I could try to make the signal sampling more stable?

- Is there any configuration value from the script that I could tweak? Such as PLL filter, gain,...

 

Regards,

Lionel
