Intel^®LXT971A

3.3V Dual-Speed Fast Ethernet PHY Transceiver

Datasheet

The LXT971A 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). The LXT971A also provides a

Low Voltage PECL (LVPECL) interface for use with 100BASE-FX fiber networks.

This document also supports the LXT971 device.

The LXT971A supports full-duplex operation at 10 Mbps and 100 Mbps. Its operating condition

can be set using auto-negotiation, parallel detection, or manual control.

The LXT971A is fabricated with an advanced CMOS process and requires only a single 3.3V

power supply.
