Hello! I have been playing around with single pair ethernet and made an expansion card for it. I built it for the 100BASE-T1 standard but TI does have drop-in and pin-compatible replacements for 1GBASE-T1 (the last time I checked) so it should be simple enough to upgrade. I haven’t ordered or tested it yet so no guarantees that it will work. If you are interested, feel free to review it! I have the design files here.
