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.
