ADV7619 APx Port

Just wanted to verify the functionality of the audio output port (Apx) on the ADV7619.


Currently I have an ADV7619-7511 development board and am utilizing the audio output port (APx) to go to an external board using header J3.  I have it setup as follows:


(Pin 101) AP1 - Front L/R

(Pin 102) AP2 - Sub/Cen

(Pin 103) AP3 - Rear L/R

(Pin 104) AP4 - Surround Back L/R

(Pin 106) AP5 - LRCK

(Pin 105) SCK

(Pin 107) MCK


I plan to use this port to go directly to one of the McASP ports of a TI TMS320C6747 in our application.  I assume it will function like this just fine.  The only reason I ask is that I am having issues when I have all the SDATA ports (AP1-AP4) hooked up on our external board for development right now.  I am attributing our issues to the fact that we are going off board with all 7 signals and that they are also simultaneously going to the ADV7511 on the board as well.  Let me see if you have any issues with this setup.
