OC-192 receiver in standard 0.18μm CMOS

Abstract

A fully integrated OC-192 multi-rate (9.95Gb/s-10.71Gb/s) receiver uses standard 0.18/spl mu/m CMOS. The circuit consists of an input amplifier, CDR, 1:16 demux and 18 LVDS drivers. The chip exceeds SONET jitter tolerance spec by >100%. Recovered 10Gb/s clock jitter is <4mUl(rms). The input sensitivity is <50mV with 870mW at 1.8V.
