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.
