Abstract

An innovative phase detector for burst mode data recovery is presented. The problem of the random nature of the data is handled via the specific data recovery architecture, where a time-advanced version of the input data is fed to a third phase detector input. The phase detector was designed in a 0.13µm CMOS technology. Simulation results demonstrate its effectiveness for the recovery of burst mode NRZ data at 1.25Gbit/s.
