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.
