Product Description
Pericom Semiconductor鈥檚 PI3L series of logic circuits are
produced using the Company鈥檚 advanced sub-micron CMOS
technology, achieving industry leading performance.
The PI3L301D is a 16- to 8-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 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.
Applications
鈥?Dual Physical Layer Device sharing to one interface
connector
鈥?SONET OC-12(622Mbps) signal routing
鈥?Routes physical layer signals for 10/100/1000 Mbit Ethernet
