Hi
does anybody have some experience with DVI output using Chrontel DVI transmitter (CH7301)
the DVI transmitter works in analog RGB bypass mode OK, I see a pong game on analog monitor
but in DVI mode there is nothing on the output, even DVI Clock is missing, DVI hotplug detect works, eg the DVI transmitter shuts down when I unplug the connector except that I can see nothing that tells me anything why the DVI transmitter is not sending anything. All voltage levels seems to correct, the bias voltages are ok, XCLK is 25MHz H/V Sync DE I think are also valid.
Chrontel datasheet doesnt tell much, I have set the DVI power control bits to active, and there doesnt seem to be any secret sequence to enable the DVI output

PS if someone is able to provide consulting help that helps me to get the CH7301 working I may be able arrange a free eval board with CH7301+V4 as thank you gift. At least I will do my best to arrange it.
