Gigabit Ethernet LAN Switch with Single Enable
1
Description
The PI3L301D-A is a 8-Channel, 2:1 multiplexer/demultiplexer
LAN Switch. Industry leading advantages include a propagation
delay of less than 250ps, resulting from its low channel resistance
and I/O capacitance. The device multiplexes differential outputs
from a Gigabit Ethernet transceiver (PHY) device to one of two
corresponding B1 or B2 outputs. The switch is bidirectional and
offers 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 10/100/
1000 Base-T (Ethernet).
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.
