DS25CP152,pdf datasheet (3.125

The DS25CP152 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.
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 return losses,
reduce component count and further minimize board space.
