DESCRIPTION

The DS10CP154A is a 1.5 Gbps 4x4 LVDS

crosspoint switch optimized for high-speed signal

routing and switching over 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 switch configuration can be accomplished via

external pins or the System Management Bus

(SMBus) interface. In addition, the SMBus circuitry

enables the loss of signal (LOS) monitors that can

inform a system of the presence of an open inputs

condition (e.g. disconnected cable).

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 return losses, reduce component count and further minimize

board space.
