Understanding of ADV7611 Video Clock generation

Hi All,


I need to understand the following related to ADV7611 LLC clock generation.


1. Is the LLC clock being derived from the HDMI TMDS clock? 

2. Are the audio and video clocks both synchronized to each other?

3. In case, I would like to synchronize LLC clocks of two different ADV7611 devices (may or may not be connected to same HDMI source) how is this possible?

   3a. I believe if answer to 1 is Yes, then this won't be possible. Since XTAL clock of 28.63636MHz clock is not being used for LLC clock generation. Please confirm.
