ADV7186 DDR2 control and Digital video input overlay problem

Hi all,

We have some problems about ADV7186.

We have an application on digital video input overlay.

So, we will use CVBS-in as video source1 , digital video input as video source2.

When we enable frame TBC on CVBS-in picture, the CVBS-in picture will disappear.

it is stragne, the CVBS-in picutre should be normal when we enable frame TBC.

So,our question is how to verify ADV7186 already can access DDR2 correctly????

Because we don't see any related register on ADV7186 spec.

 

Regards,

Mindy
