AD9889B: 1080P video flickering

Hi ,


We are using AD9889B.


I am able to display 480p, 720p, 1080i in RGB mode 24bit per pixel. I have to display in 1080p (VID 16).

It is only picture display without any audio.


With 1080p, I am sending same image continuosly. But, TV displays the image for sometime(may be less than half a second) and then a junk frame is displayed and then TV goes blank. This pattern is repeated continuously. TV is detecting the 1080p timing correctly.

AD9889B is also detecting input VID correctly.


I have measured the pixel clock and it is 148.5Mhz.

Any idea on what can be the reason for the flicker?
