From the project

Zynthian hardware stuff: PCBs, schemes, parts specifications, pin assignment, ...

ZynADAC is an Input/Output Audio Interface for the RBPi.

+ Burr Brown (Texas Instruments) PCM5242 (DAC) + Burr Brown (Texas Instruments) PCM1863 (ADC) + 2 x ultra-low jitter oscillators (44.1 & 48 KHz) + 3 x dedicated ultra-low noise LDOs (analog DAC, analog ADC, digital)

This design is inspired in the Hifiberry soundcards.
