A 5Gb/s NRZ transceiver with adaptive equalization for backplane transmission

The proposed 5Gb/s transceiver has a transmitter with 2-tap pre-emphasis and an adaptive receiver with 1-tap feedforward and 3-tap decision feedback equalization. The quad transceiver occupies 12 mm/sup 2/ in 0.13 /spl mu/m CMOS, consumes 2.1 W from 1.2 V, and has a BER<10/sup -15/ over 4 pairs of 1-meter backplane trace with crosstalk.
