DS10CP154

1.5 Gbps LVDS Crosspoint Switch

General Description

The DS10CP154 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 in-

tegrity 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 device insertion and

return losses, reduce component count and further minimize

board space.
