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.
The ST3DV520E is a bidirectional switch designed for multiplexing and demultiplexing differential LVDS signals and DDC channels. It supports up to four differential LVDS channels and two DDC channels, allowing for independent selection of input paths via control pins.
