.Da The Intel® LXT972A Single-Port 10/100 Mbps PHY Transceiver (called hereafter the
w LXT972A Transceiver) directly supports both 100BASE-TX and 10BASE-T applications. The
w LXT972A Transceiver is IEEE compliant and provides a Media Independent Interface (MII) for
easy attachment to 10/100 Media Access Controllers (MACs). The LXT972A Transceiver
w supports full-duplex operation at 10 Mbps and 100 Mbps. Operating conditions for the
mLXT972A Transceiver can be set using auto-negotiation, parallel detection, or manual control.
The LXT972A Transceiver is fabricated with an advanced CMOS process and requires only a
osingle 2.53.3 V power supply with 2.5 V MII interface support.
