With TVP7002, 1080P 60fps video input was used.

The VSYNC output from TVP7002 has a problem as below scope image.

 

 

Can you guess why the VSYNC output shows error?

 

Thanks and regards,

Hayden

    Hayden,

    Check all registers are set correctly. You can use the setup files from the TVP7002EVM product page located here...

    Open the command file for the mode you are using the TVP7002 in and search for '1080p60' for the additional registers which need to be set. Note that the top of the file describes some default registers which need to be set for all modes too.

    BR,
