Fully-integrated SONET OC48 transceiver in standard CMOS

Abstract

A fully-integrated transceiver in standard 0.18 /spl mu/m CMOS exceeds all SONET OC-48 requirements. The serial interfaces are 2.488 or 2.667 Gb/s CMC and the parallel ones are 622 or 666 Mb/s LVDS. The output clock rms jitter is 1 ps and total power consumption including all the input/output interfaces is 500 mW.
