Abstract :
A 2.5-Gb/s phase-lock clock and data recovery (CDR) circuit is proposed in system simulation for SONET OC-48 (2.488/2.666-Gb/s) transceiver applications. The CDR circuit exploits 1/4-rate linear phase detector. Making use of this technique the design of voltage controlled oscillator (VCO) facilitates and also it eliminates 1:4 demultiplexer and frequency divider since this topology directly produces recover data.
