I am using a AD9398 in a new design, but I am have difficulty is configuring the part. I am not using HDCP and thus those pins are not connected. When I bring the part of our reset, I can see activity on the output Syncs, Clocks lines, video data lines. This activity is occuring before we connect the HDMI cable to the board. Is this normal??? When I do connect the HDMI cable, the Syncs, Clock, and data lines signal do not look correct. For example the video coming on the HDMI cable is running at 1280x1024 at 60Hz, and I expect to see a very nice VSYNC at 16ms intervals but I dont.
Can anyone shed some light on how to use this part.
