STMUX1000L Datasheet | STMicroelectronics

CRIPTION The STMUX1000L is a 16 to 8 Bit multiplexer/ demultiplexer low RON bidirectional LAN Switch designed for various standard, such as 10/100/ 1000 Ethernet. 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 16Ω switches, S.P.D.T. (Single Pole Dual Throw Channel), for LED supporting. ..
