Pericom Semiconductor’s PI3Lseries of logic circuits are produced
using the Company’s advanced sub-micron CMOS technology,
achieving industry leading performance.
The PI3L110 is a 8- to 4-bit 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. The device multiplexes differential
outputs from a Fast Ethernet transceiver (PHY) device to one of
two corresponding 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
Base-T (Ethernet).
Generally, this part can be used to replace mechanical relays in
Applications
• Dual Physical Layer Device sharing to one interface
connector
low-voltage LAN applications that interface a physical layer over
CAT 5 or CAT 6 unshielded twisted pair cable through an isolation
transformer.
