ADV7391 Power Supply & Grounding

I'm using ADV7391 to convert BT.656 video signals from imX.6 procesor to analog composite video in our Wifi Display project.

I've designed the schematics.

I've seen in the Evaluation board schematics that all the power rails being separated with different reference grounds.

I've designed with only the common ground & an analog ground.

The power rails are all filtered separately.


I'm attaching the schematics page here. Please review it & tell me if I've to make any changes especiall with regard to filter design & reference grounds.
