No outputs from ADV7611

Hi,

 

I have big problems to get the ADV7611 circuit to run correct.

We are usin 3 ADV7611 circuits to interface 3 different video sources.

The ADV7611 we are using is without HDCP.

I have confirmed that the device givs ack for each config. command I send.

I'm using a 28.6363 MHz X-tal. The default register settings is 28.6363 MHz so i suppose I don't tp write to that register?

Clock termination is enabled and disable of Tristate pins is enabled.(= The Tx source is transmitting).

 

I have the LLC clock output running(=Tx source Pixelclock) but there is NO pixel data or sync signals(HS,VS,DE)on the output!

When I set the register in FreeRun (and have no input source) I get sync signals on output so it looks like the HW is allright.

 

My register settings are:    

                                                  Map addresses

 

                                                  98 F4 80 ; CEC

                                                  98 F5 7C ; INFOFRAME

                                                  98 F8 4C ; DPLL

                                                  98 F9 64 ; KSV

                                                  98 FA 6C ; EDID

                                                  98 FB 68 ; HDMI

                                                  98 FD 44 ; CP

                                   68 85 1F ; ADI recommended setting

                                   68 87 70 ; ADI recommended setting

                                   68 57 DA ; ADI recommended setting

                                   68 58 01 ; ADI recommended setting

 

All other register settings are kept default. Have I missed something? Is the order of setting up the registers important?

This is VERY,VERY URGENT. We have a dead-line TODAY, so PLEASE someone!!!

 

Best Regards
