7611 12bit 422 DDR Mode

Hello all,

we are using the AVD7611 HDMI RX and try to configure it for 12bit DDR 4:2:2 Mode 2. The 7611 is connected to our FPGA.

Our problem is that no CbCr values are getting transferred. Luminance is fine but the colors are missing.

 

Thanks for any help or information.

 

Here is a snip of the configuration:
