ESI Juli@ analog card interface details

Posted 15th May 2014 at 04:21 PM by 1audio

Attached is a decode of the cards interface connector to allow interfacing to external DAC's and ADC's.

I'm searching for the pins on the big Via chip that indicate the sample rate/master clock frequency. I'll post those when I find them.

    I do not read the blogs on a regular basis, so just saw this entry of yours. I believe I have the information you seek. Please contact me at my email, gstewtoo at gmail dot com so I can send you the datasheet.

    Thanks a lot for the information, it's very helpful.

    There might be an error or two with the pinout.

    - J3 pin 19 probably isn't "hpf enable" but cks1 (pin 16 on the adc).
    - J3 pin 8 could be used to send a mute signal 60ms after a fs change. The rest of the time, it would indeed show dvdd as the mute pin would be "H".

    This overall schematic can be useful too: https://www.ixbt.com/multimedia/esi/julia/scheme-big.png
