Intel^®LXT972M Single-Port 10/100 Mbps

PHY Transceiver

Datasheet

The Intel^®LXT972M Single-Port 10/100 Mbps PHY Transceiver is an IEEE compliant Fast

Ethernet PHY Transceiver that directly supports both 100BASE-TX and 10BASE-T applications. It

provides a Media Independent Interface (MII) for easy attachment to 10/100 Media Access

Controllers (MACs). Both full and half-duplex operation at 10 Mbps and 100 Mbps is supported.

Operation mode can be set to auto-negotiation, parallel detection, or manual control. The device is

powered from a single 3.3V power supply.

Applications

■ Combination 10BASE-T/100BASE-TX

Network Interface Cards (NICs)

■ Wireless access points

■ 10/100 Personal Computer Memory Card

International Association (PCMCIA) cards

■ Cable Modems and Set-Top Boxes

■ Network printers

Product Features

■ 3.3V Operation
