ADV7511 TMDS Clock Inversion

Question asked by hderby on May 5, 2012

We're working with the ADV7612-ADV7511 eval board, and we noticed that the ADI scripts for this board (Version 2.9c) set the TMDS clock inversion bit (Main page address 0xDE bit 3).  This is not recommended in revision E of the ADV7511 programming guide.

 

I was wondering why the clock inversion bit is set.  As near as I can tell, there is no requirement on the phase of the TMDS clock,so either state is probably valid, but I would like to know why this bit was set in the script.

 

Thanks,

 

Howard
