4, 8 and 12 port 155 mbps to 4.25 gbps crosspoint switches with cdr VSC3204,vsc3208,vsc3212 the vsc32xx series is a set of cdr crosspoint switches designed to regenerate and switch any non-return to zero (nrz) serial data stream. with a single reference clock input, the vsc32xx switches operate at binary multiples of a base data rate between 155 mbps and 4.25 gbps. a fully nonblocking, multicast architecture allows the vsc32xx to be user-configured via simple two-wire or four-wire serial interfaces for a broad range of applications. a high degree of signal integrity is maintained by means of configurable input and output equalization. the integrated equalization circuits are optimized to compensate for deterministic jitter that often results from lossy cabling and printed circuit board traces. these devices are tailored for high-speed serial signals used in serial copper interconnect applications such as multi-connector backplanes, box-to-box cabling as well as basic signal clean up throughout high speed systems. general description: 741 calle plano camarillo, ca 93012, usa tel: +1 805.388.3700 fax: +1 805.987.5896 www.vitesse.com for more information on vitesse products visit the vitesse web site at www.vitesse.com or contact vitesse sales at (800) vitesse or sales@vitesse.com ?2004 vitesse semiconductor corporation vitesse, asic-friendly, fibretimer, timestream and snoop loop are trademarks of vitesse semiconductor corporation. all other trademarks or registered trademarks mentioned herein are the property of their respective holders. vitesse semiconductor corporation ("vitesse") retains the right to make changes to its products or specifications to improve performance, reliability or manufacturability. all information in this document, including descriptions of features, functions, performance, technical specifications and availability, is subject to change without notice at any time. application diagrams: VSC3204 loopback/ failover switch txcvr line processing txcvr signal switching / routing application signal conditioning in fiber transmission vsc32xx vsc32xx fiber optic transceiver fiber optic transceiver fiber optic transceiver fiber optic transceiver data path of unknown characteristic (rj & dj) up to 0.4ui of total jitter recovered data recovered data fiber-induced jitter fiber-induced jitter
