Description

Pericom Semiconductor’s PI5L200 is a Rail-to-Rail Quad 2:1

multiplexer/demultiplexer LanSwitch with 3-state outputs. The On-

Resistance typically varies from 5 ohms to 7 ohms with data inputs

of 0V to 5V. Generally, this part can be used to replace mechanical

relays in low voltage (3.3V/5V systems) LAN applications.

With a wide bandwidth of 135 MHz, the PI5L200 can switch Fast

Ethernet and ATM25 signals. Into 100-ohm UTP cables, the switch

distortion is typically less than two percent. Crosstalk @30 MHz is

–70dB. The PI5L200 operates from a single 3.3V/5V supply and

interface to TTL logic.

Applications

• 10/100 Base-TX/T4

• 100VG-AnyLAN

• Token Ring 4/16 Mbps

• ATM25

• NIC Adapter and Hubs

• SONET OCI 51.8Mbps

• T1/E1
