Abstract :
A 9.953 to 12.5Gb/s MLSE receiver consisting of an AFE IC in a 0.18mum 3.3V ft=75GHz, and a digital IC in a 0.13pm 1.2V CMOS is presented. The AFE IC features a 7.5GHz 40dB VGA, a 4b 12.5GS/S ADC, a dispersion-tolerant clock-recovery unit, and a 1:8 DEMUX. The digital IC implements an 8-parallel, delayed recursion MLSE architecture and a nonlinear channel estimator. The 4.5W receiver meets the SONET jitter specifications with 2200ps/nm of dispersion at BER=104
