What about the plethora of LVDS receivers - they're basically a
differential input thresholder, with deliberate hysteresis, looking for
a 300 mV shift across a 100 ohm resistor.
I played with that, I used a small transformer to balance the signal
and then into LVDS receiver through a voltage divider. Worked well,
but I didn't measure the jitter, it was just for a micro-controller.
You can also do it with capacitive dc block to one side, and some
resistors - the ap notes describe it. The receivers are a fairly high Z
input, so you pick the voltage divider resistors to make the termination
resistance right for the incoming signal.
