A Serial-Link Transceiver with Transition Equalization

Two transition-equalization techniques are proposed. A pulse-overlapping half-symbol tap FIR transmitter is able to equalize a 120-inch 40dB attenuation FR4 with BER of <10
^-13
at 3.7Gb/s. A DFE with transition ISI cancellation performs better than traditional DFE and achieves a BER of <10
^-12
at 3.6Gb/s with 80-inch FR4
