The DS25CP102Q 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 DS25CP102Q 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.
