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