TDA1540 - I2S to Offset Binary for Intel Altera CPLD/FPGA

@eclipsevl yes, that's as I understand it

I'm looking for a solution or would love to collaborate to find one that would do I2S to offset binary output for 4 TDA1540 in the way you show above. Two for the left and two for the right.

The only one I know of that states it can do it is the SAA7030 TDA1540 Driver Module Support I2S 256fs 384fs Input Balanced Output board

I just received one yesterday to try. I'm a few weeks away as I am waiting on some of Miro's 1540 boards (should be here today or tomorrow). I have the JL Sounds USB board and Amanero to try. I just need to build all the power supplies and then I'll be ready to test and try.
 
I know SAA7030 did what was necessary to communicate with the TDA1540 so I ordered this from aliexpress

I wanted to hear the difference side by side between the two devices. My ultimate goal is to get a TDA1540 based DAC working with I2S input and a balanced analog output. The board from aliexpress with the SAA7030 ouputs an inverted signal for left and right so I'm going to try that with one miro board to make sure stereo is working, then a second to see if it'll work as a balanced DAC with 2 boards and 4 chips. If that works then I'd like to work with somebody to get the code for the CLPD device working with a balanced setup.
Could you tell me what the function is of this board cause I can't figure it out.
