The VSC3104 is a 4x4 Crosspoint Switch with
Integrated Equalization
The VSC3108 is a 8x8 Crosspoint Switch with
Integrated Equalization
Making next-generation networks a reality.
The VSC3104/3108 are multipurpose switching devices that are
designed to enable next generation backplane designs, and extend the
life of existing backplanes. The integrated equalization capabilities
at both the input and output effectively absorb the effects of signal
loss through copper interconnect, either printed circuit board traces,
or cable.
The function of the VSC3104/3108 is simple, yet powerful, creating
multiple applications just about anywhere high-speed signals are
present. The fully broadband, non-blocking and multi-cast capable
switch core allows the VSC3104/3108 to be congured as a 1:4/1:8
fan-out buffer with very low channel-channel skew, or as a 4/8 channel
signal reconditioner.
