8.5 What is clock and data recovery?

Retimers are a key building block in communication systems involving high-speed data transmission. The use of clock and data recovery, or CDR, provides improved clock and data synchronization and also reduces timing uncertainty. In addition, CDRs are valuable as a means of jitter mitigation for a variety of applications.  In this video, we’re going to discuss the clock and data recovery function and key metrics used to evaluate a CDR in retimer products.
