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.
