A 10-Gb/s CMOS clock and data recovery circuit with a half-rate binary phase/frequency detector

摘要

A 10-Gb/s phase-locked clock and data recovery circuit incorporates a multiphase LC oscillator and a half-rate phase/frequency detector with automatic data retiming. Fabricated in 0.18-Μm CMOS technology in an area of 1.75×1.55 mm2, the circuit exhibits a capture range of 1.43 GHz, an rms jitter of 0.8 ps, a peak-to-peak jitter of 9.9 ps, and a bit error rate of 10-9 with a pseudorandom bit sequence of 223-1. The power dissipation excluding the output buffers is 91 mW from a 1.8-V supply.
