ADV7611 LLC problem

Question asked by VEP10 on Apr 30, 2013
Latest reply on May 3, 2013 by VEP10

I want to receive with ADV7611 TMDS signals of the following resolutions: 720x576i/480i, 720x576p/480p, 1280x720p, 1920x1080i.

I tested almost all scripts adviced in the threads of ADV7611 without success.

First I want to receive 720x576 50i format HDMI signal. In this case the frequency of the TMDS clock is 27 MHz. (I tested the input signal and it is ok.) But the frequency of the signal at the LLC pin is always 25.1748 MHz instead of 27 MHz and the chip cannot output correct data. The clock frequency of the chip is 28.63636 MHz.

What do you think which register setting is incorrect?

 

Thanks,

Peter
