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.
