Almost all modern fast serial interfaces are descended from ECL. Often with a twist that while receiver is ECL/CML-style long-tailed pair (which is the obvious implementation of comparator), the transmit side is normal CMOS totem-pole output stage coupled with some passive network to produce right voltage levels (and right output impedance).
