Default PS Audio I2S interface

I'm trying to connect a PS Audio Perfect Wave Transport to an Audio GD Master 7 via I2S. Does anyone have the pinouts for the PS Audio I2S HDMI connector and the Master 7 I2S RJ45 connector Thanks Marc

I am very interested to know if you had any success connecting your Perfect Wave transport to your Audio GD DAC via I2S as I have an Audio GD dac also that has RJ45 I2S input and am wondering if my Sony CD player that has HDMI I2S digital out can be connected.

Hi, marcmccalmont!

I am not familiar with Audio GD DAC. According to the description "3.3V" on the picture you showed, their I2S seems to be CMOS Level compatible and single ended. As you may know, PS Audio I2S interface is based on LVDS with differential.
I'm afraid that you might have no good result.

In general, you need such a level converter from LVDS to CMOS;

(This schematic shows examples of PS Audio type transmitter and receiver designed by Fidelix company in Japan. The receiver includes an additional I2S isolator.)
