A 3.125-Gb

A 3.125-Gb/s clock and data recovery (CDR) circuit using a half-rate digital quadricorrelator frequency detector and a shifted-averaging voltage-controlled oscillator is presented for 10-Gbase-LX4 Ethernet. It can achieve low-jitter operation and improve pull-in range without a reference clock. This...
