Description
The ST3DV520E is a 4 differential channel LVDS
multiplexer/demultiplexer low R_ON bidirectional
switch used to switch between multiple LVDS
sources. It is designed for very low crosstalk, low
bit-to-bit skew and low I/O capacitance, to
maintain high signal integrity.
The differential signal from the LVDS transceiver
is multiplexed into one of two selected outputs
while the unselected switch goes to Hi-Z status.
The device integrates 2 SPDT (single pole dual
throw) switches, for DDC channel.
SEL for LVDS and DDC channel is controlled
independently.
