CAES UT54LVDM228 LVDS Crosspoint Switch

The UT54LVDM228 is a quad 2x2 cross point switch utilizing Low Voltage Differential Signaling (LVDS) technology for low power, high-speed operation. 

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. 

The UT54LVDM228 was designed for high-speed differential cross point, 2:1 mux, 1:2 demux, repeater or 1:2 signal splitter.  The mux and demux functions are ideal for switching between primary and backup circuits in fault tolerant systems and the signal splitter and mux functions are useful for distribution of a bus across several rack-mounted backplanes.
