The bandwidth demands of modern computing systems have been continually increasing and the recent
focus on parallel processing will only increase the demands placed on data communication circuits. As data rates
enter the 2.4Gb/s range, serial data communication architectures become attractive as compared to parallel
architectures. Serial architectures have long been used in fiber optic systems for long-haul applications, The
integration of clock and data recovery circuits into monolithic integrated circuits is attractive as it improves
performance and reduces the system cost, The functionality and implementation of these circuits will be checked in
LTspice using standard 45nm CMOS technology.
