adv7842 eval board cvbs input

Hello

 

Am using adv7842-adv7511 eval board to test the 480i cvbs input.The 36 bit 4:4:4 output script for cvbs with some modifications is giving a proper output. but when i run the 16/20/24 bit separate sync subscripts small waves are appearing in the video frames continuously. however the waves are not there for 8/10/12 bit separate syncs.why does this happen? Also none of the embedded sync subscripts are working. is any tuning required in the hsync/vsync duration and placement values in adv7511 for the embedded sync scripts to work?

 

Regards

PG.
