The communication links at high speed requires bit synchronizer for countering bit phase misalignment at the receive end. This paper describes the design of IC based digital bit synchronizer for high speed optical communication links. It supports data rate from 10 Mbps to1 Gbps. The design shows the excellent jitter and eye performance with an eye opening of 95.5% at data rate of 1Gbps. The test results shows that worst case total root mean square jitter is 28.6 picoseconds exceeding the nominal standards of SONET jitter requirements.
