Hi francolargo,
Thanks for that quick response.
The DAC is under warranty, so I really shouldn't open it up and modify it just yet.
I'm guessing the PS Audio receiver is a DS90LV032A (but that's not a certainty). I'll study the specs later and see if I'm feeling lucky. I'm hoping somebody has tried this.
It's also looking like I can buy a cheap card meant for driver LCD displays that has an LVDS driver on it. That may be the way I go.

At first glance they seem compatible. M-LVDS is slower but still more than fast enough and a more tolerant input circuit. More here: https://www.analog.com/media/en/technical-documentation/application-notes/AN-1177.pdf There is no obvious reason why they won't just work together for I2S. 100 Mbps is still much faster than needed for I2S.
The real issue is that the RJ-45 pin mapping is not the same. This can be overcome with a custom cable.
We designed the Teleporter to fully utilize the twisted pairs of the ethernet cable with the LVDS differential signals. I am not sure how PS Audio did theirs, but I know they are different.

Hi Brian,
Yes, custom cable is what I'm prepared for. There's several sources of an excel file that shows how many brands implement i2s, including PS Audio. That indicates (correctly I hope) that they use the older LVDS and a DS90LV032A as the receiver.
Have you heard of any interface issues connecting the Teleporter to the older LVDS chips?
Thanks,
Hugh
