DESCRIPTION
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.
The DS90CP22 accepts LVDS signal levels, LVPECL
levels directly or PECL with attenuation networks.
The individual LVDS outputs can be put into TRIPackages
STATE by use of the enable pins.
