ADV7511 parallel YUV 8 bit from camera capture problem

Hi.

We have EVAL-ADV7612-7511. It worked with Analog Devices script "HDMI in to HDMI out". But we want to enable ADV7511 to input parallel 8 bit YUV 4:2:2 parallel bus from camera to HDMI. We wired this bus to the ADV7511 input and it didn't work. Can this chip support this bus? This bus has 8 bit data, HSYNC, VSYNC and PCLK. Our bus doesn't have DE signal so I tied it to 3.3V. I configured the registers due to your hardware document (right justified, 8 bit and YCbCr 4:2:2 with separated sync). Can you advice why it doesn't work.

Thanks.

Michael.
