INTRODUCTION
The UT54LVDM228 is a quad 2x2 crosspoint switch utilizing
Low Voltage Differential Signaling (LVDS) 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 on each switch. LVDS I/O
enable high speed data transmission for point-to point or multi-
drop 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 a bus across several rack-mounted
backplanes.
The individual LVDS outputs can be put into Tri-State by use
of the enable pins.
All pins have Cold Spare buffers. These buffers will be high
impedance when VDD is tied to VSS.
