A 0.6-2.5 GBaud CMOS tracked 3/spl times/ oversampling transceiver with dead-zone phase detection for robust clock/data recovery

Tracked 3/spl times/ oversampling with dead-zone phase detection is used in a receiver for robust clock/data recovery in the presence of excessive jitter and ISI. The transceiver, in 0.25 /spl mu/m CMOS, operates at 2.5 GBaud over 10 m 150 /spl Omega/ STP cable and at 1.25 GBaud over 25 m with <10/sup -13/ BER.
