Single-Port 10/100 Mbps PHY Transceiver

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.
