Getting AD9889B to work with 800x480 video input

We are trying to use the AD9889B to feed a 800x480 RGB888 video stream (with separate syncs) to a HDMI display (format RGB 4:4:4).

 

We have computed appropriate values for a few registers (documented in the quick start guide) and we programmed them. Our first few attempts have yielded no results, so I am looking for quick feedback on how we could get this working.

 

At this point, I have a couple of questions:

  - does the AD9889B support this resolution ? (800x480 @ 60 Hz) can we get this resolution working without issues ?

  - would we need to compute values for DE generation to get this to work ?

 

Thanks !
