DS90CP22,pdf datasheet (800 Mb

DS90CP22 is a 2x2 crosspoint switch utilizing LVDS (Low
Voltage Differential Signaling) technology for low power, high
speed operation. Data paths are fully differential from input to
output for low noise generation and low pulse width distortion.
The non-blocking design allows connection of any input to any
output or outputs. LVDS I/O enable high speed data transmission
for point-to-point interconnects. This device can be
used as a high speed differential crosspoint, 2:1 mux, 1:2 demux,
repeater or 1:2 signal splitter. The mux and demux
functions are useful for switching between primary and backup
circuits in fault tolerant systems. The 1:2 signal splitter and
2:1 mux functions are useful for distribution of serial bus
across several rack-mounted backplanes.
