(R) PRODUCT BRIEF VSC3104 VSC3108 The VSC3104 is a 4x4 Crosspoint Switch with Integrated Equalization The VSC3108 is a 8x8 Crosspoint Switch with Integrated Equalization 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 configured as a 1:4/1:8 fan-out buffer with very low channel-channel skew, or as a 4/8 channel signal reconditioner.
