The Intel

LXT970A Dual-Speed Fast Ethernet Transceiver (called hereafter the LXT970A

Transceiver) is an enhanced derivative of the Intel

®

LXT970 10/100 Mbps Fast Ethernet PHY

Transceiver that supports selectable driver strength capabilities and link-loss criteria. The

LXT970A Transceiver supports 100BASE-TX, 10BASE-T, and 100BASE-FX applications. It

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

Controllers (MAC)s and a pseudo-ECL interface for use with 100BASE-FX fiber networks.

The LXT970A Transceiver supports full-duplex operation at 10 and 100 Mbps. Its operating

condition is set using auto-negotiation, parallel detection or manual control. The encoder may be

bypassed for symbol mode applications.

The LXT970A Transceiver is fabricated with an advanced CMOS process and requires only a

single 5V power supply. The MII may be operated independently with either a 5V or a 3.3V

supply
