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.
