4, 8 and 12 Port 155 Mbps to 4.25 Gbps Crosspoint Switches with CDR
GENERAL DESCRIPTION:
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.
