Merci, mais je n'ai pas encore tout compris.
Pour cette partie "Rpi-> HAT/I2S ", Allo dit

Citation :Via email, Iaon B. elaborates: “We took a Raspberry Pi I2S signal, we made a S/PDIF stream, we then pass it through a galvanic isolator IC and on the other side we re-clock the S/PDIF stream with a very clean clock. In the end, we arrived at a output of less than 1ps of jitter and noise under 10uV….”.
