AD9889B: YCbCr422 Separate Sync Issue

Hi,

Using AD9889B, I have configured for YCbCr422 24bpp separate sync. However, I see HDMI generates Embedded sync parity error interrupt.

I am trying to display 480p to start with.

 

RGB444 and YCbCr444 works well.

 

Below is my register dump for AD9889B in YCbCr422 separate sync configuration. Can you point if there are any wrong register configurations?
