I would imagine "low power bidirectional isolators" are the last things you would want to use here. Whatever buffers you include to split the signal will introduce jitter and subsequent reclocking will, at least in concept, be needed if you aim for a low jitter system. Otoh, i cannot imagine the need for a low jitter I2S signal at the input of the miniDSP - what you need is a reclock after the DSP. |

Just realised the miniDSP does not have I2S outputs, so reclocking is obviously not possible.
Maybe Joro can advise on a suitable buffer ic for the MCK. The other signals... i wonder if both inputs cannot be supplied from the same set of outputs with just separate inline resistors... |

ISO1540 is not proper for I2S, it's too slow. If I haven't miss something from the link: Quote:

just discovered this thread ... will put myself on the GB tread for your XMOS board as is, but if you could implement the timings for the PCM56, that would be a clear additional value! So one more further encouragement from my side for the implementation! Also, if there would be an option to directly power the board from external 3.3V (A123 LiFoPo), that would be very welcome as well! Keep up the good work, Abel |

I will be immensely grateful if you can show me an example with a circuitry to give me a better understanding of what you are talking about! May I thank you in advance! Last edited by CheerfulYC; 16th August 2013 at 06:53 PM. |
