EVAL - Melody 8. Using the Extender pins on the CPLD to drive audio externally

Category: Hardware
Product Number: EVAL-MELODY-8

There is a 60 pin header in my EVAL Board:

 

I want to drive audio from the cpld that goes into the  in-built dac (1939) through the extender pins to route it to my own external dsp, dac setup. like in the image below:

thanks.
