Description

e PI3L2500 is an eight-channel 2:1 multiplexer/demultiplexer LAN

switch with Hi-Z outputs. Industry leading advantages include a

propagation delay of less than 250ps, resulting from its low-channel

resistance and I/O capacitance. e device multiplexes dierential

outputs from a Gigabit Ethernet transceiver (PHY) device to one

of two corresponding B or C outputs. e switch is bidirectional

and oers little or no attenuation of the high-speed signals at the

outputs. It is designed for low bit-to-bit skew, high channel-to-

channel noise isolation, and is compatible with various standards,

such as 1000/2500/10000 Base-T (Ethernet).

e PI3L2500 provides a Power Down input (PD), which can put

the device into standby mode (PD = 1) while mobile, eliminating

an external power switch.

Generally, this part can be used to replace mechanical relays in

low-voltage LAN applications that interface a physical layer over

CAT 5 or CAT 6 unshielded twisted pair cable through an isolation

transformer.
