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. Table 1.
