It is designed for very low Cross Talk, low bit to bit skew and low I/O capacitance. The differential signal from the Gigabit Ethernet Transceiver is multiplexed in one of two selected output while the unselected switch go to Hi-Z status. The device integrates three 16 switches, S.P.D.T. (Single Pole Dual Throw Channel), for LED supporting.
