DESCRIPTION
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.
