Abstract :
A 10Gbps, 1/5-rate burst mode clock and data recovery (BMCDR) circuit is proposed. The BMCDR is reconfigurable between data gating mode and phase tracking mode to achieve instantaneous phase-locking with jitter suppression for 10 GPON. Incorporating a 1/5-rate CDR with 1:5 demultiplexer, it achieves a high energy efficiency of 1.24pJ/bit. With a 4MHz, 0.22UIpp input data jitter, the recovered clock jitter at 2GHz is 2.94psrms. The prototype chip is fabricated in UMC 55nm CMOS technology. Chip size is 200×150μm2.
