DS25CP102Q
Automotive 3.125 Gbps 2X2 LVDS Crosspoint Switch with
Transmit Pre-Emphasis and Receive Equalization
General Description
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 bal-
anced cables. Fully differential signal paths ensure excep-
tional 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 trans-
mit 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.
