Description

The ST3DV520E is a 4 differential channel LVDS

multiplexer/demultiplexer low RON 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.
