Clock & Data Recovery Solutions
Overview
Gennum’s world-class expertise in the design of high-performance clock and data recovery (CDR) ICs
oers best-in-class performance in the key areas of power consumption, receiver sensitivity, output jitter
and jitter tolerance. Leveraging Gennum’s ClearEdge™ technology, our innovative, low power CDRs
provide the industry’s best jitter performance which is a key advantage in designing next-generation optical
transceivers, copper cable interconnect and backplane interconnect applications. Additionally, Gennum’s
CDRs operate without a reference clock and use a single 3.3V supply, minimizing system and module costs.
