DESCRIPTION
The DS25CP102 is a 3.125 Gbps 2x2 LVDS crosspoint switch optimized for high-speed signal routing and
switching over lossy FR-4 printed circuit board backplanes and balanced cables. Fully differential signal paths
ensure exceptional signal integrity and noise immunity. The non-blocking architecture allows connections of any
input to any output or outputs.
The DS25CP102 features two levels (Off and On) of transmit pre-emphasis (PE) and two levels (Off and On) of
receive equalization (EQ).
Wide input common mode range allows the switch to accept signals with LVDS, CML and LVPECL levels; the
output levels are LVDS. A very small package footprint requires a minimal space on the board while the flow-
through pinout allows easy board layout. Each differential input and output is internally terminated with a 100Ω
resistor to lower device insertion and return losses, reduce component count and further minimize board space.
