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.
