Hello. Some time ago I posted a topic about a DAC Wing that I made (using the MAX5556), and well... So far it has been a total failure. I don't know if I damaged the chip while soldering or what is happening, but it simply does not respond (I soldered 2 and none of them seem to work). That's why I decided to try a different chip. This time I chose a PCM1754 from Texas Instruments. And since I also decided to manufacture the PCB with Elecrow (last time it was with OSHPark), I had some room left, so I decided to throw in an ADC as well, making it a CODEC Wing . The ADC is a PCM1808, and to generate the proper clock signals for standard sampling rates (44.1kHz, 48kHz, etc.) I used a PLL1705. Here is the render of the PCB I'll attatch the schematic as well. What do you think? Here is the link of the github of the deisgn files and stuff https://github.com/DiegoRosales/PCB_Designs/tree/master/CODEC%20Wing CODEC Wing Schematic Rev 1.0.pdf
