I'm using the AD7612 HDMI receiver. All is working fine except when I use a YCbCr 4:2:2 HDMI input. I have no problems with RGB 4:4:4 and YCbCr 4:4:4. The problem is that the colors in 4:2:2 are changed using a simple bar pattern as video input. The white is changed to yellow, the yellow to light green, ...

Is there any limitation in this IC to work with a YCbCr 4:2:2 input ?.

My output is YCbCr 4:2:2 to the BT.656 bus. I tried to change most of the registers related to color space, kind of input but without success.
