New Head-Fier
What I wrote is correct. I have built and used this configuration several times.Only the second link.
The first one has nothing to do with HDMI. It takes an input from the RJ-45 connector. Not the output as is needed. Secondly, it is intended for use with older DAC models which have on-board 5-pin I2S TTL level socket. It will work with single-ended I2S source, not guaranteed working with differential I2S source. Website makes a relevant remark.
The board in the first link has an HDMI connector as an input and converts the i2s from LVDS to single i2s. This converts the HDMI/LVDS output of the Di20HE back to normal i2s.
The board from the 2nd link has no electronics whatsoever. It simply distributes the i2s output of the board to the RJ45 socket. Of course, you can also connect any other RJ45 socket to the HDMi/LVDS to i2s board, or solder a short RJ45 cable directly.
Addendum:
By the way, the parts from the first two links are nothing other than what is installed in the housing in the third link.
