The CX20464 is used to retime signals in large switch matrices. CDRs are critical elements in the SONET/SDH telecom transmission system, providing internal retiming of high-speed signals. Conexant's quad OC-48 CDR is one of very few commercially available quad 3.2 Gbps retimers, and can be used with the CX20462 and the CX20472 crosspoint switches. It enables the development of high-density switch cores, while substantially reducing the number of ICs on a single board. This also reduces power dissipation, a critical objective of today's telecom system designers.
