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.
