Intel LXT971A
(R)
Dual-speed 3.3V 10/100 Ethernet Transceiver
With Intel(R) Carrier Class Ethernet Support
Product Description High-performance network applications that demand lower power are growing rapidly in today's marketplace. Intel, a leading provider of Ethernet silicon solutions, has enhanced the commitment to its Ethernet product family with its latest 10/100 Fast Ethernet transceiver. The Intel(R) LXT971A is a next-generation low-power, single-port PHY with significantly expanded Cable Discharge Event (CDE) protection. Revolutionary design techniques incorporate Intel's Optimal Signal Processing (OSP) architecture, an ideal combination of digital signal processing and analog design techniques designed for die size, power consumption, performance, reliability, and testability. Applications
LXT971A offers a Sleep mode in addition to two Power Down modes. When the LXT971A detects an absence of energy on the twistedpair input, it minimizes power consumption by shutting down the transmitter and placing the receiver in low-power mode. Intel Carrier Class Ethernet Many networking and telecom applications require high-performance Ethernet components capable of operating under harsh environmental conditions. Intel(R) Carrier Class Ethernet products support operation over the entire extended temperature range while providing features that increase reliability. Each device has an operation lifetime of at least 10 years with less than 100 failures per billion hours. All Intel Carrier Class Ethernet devices will be available a minimum of 5 years from product introduction. The Intel Carrier Class Ethernet product portfolio includes solutions for Ethernet physical layer, switching and repeater technologies at a variety of speeds. Intel Carrier Class Ethernet products are ideal for applications where equipment must function reliably in uncontrolled environmental conditions such as base stations, telecom/network switches, factory floor equipment, and industrial computers.

Low-power, dual-speed network applications for the LXT971A transceiver include: network interface cards (NICs), PCMCIA cards, cable modems, set-top boxes and IP phones. The LXT971A includes an MII with extended register capability and an optional 2.5V power supply interface for additional power savings. For 100BASE-FX fiber networks, the LXT971A is designed with a pseudo-ECL (PECL) interface for seamless integration with common industrystandard fiber modules. Innovative Packaging Intel delivers the LXT971A in a 7mm x 7mm plastic ball grid array (PBGA) packaging. This revolutionary package helps save board space and is available in the popular industrial temperature range that is ideal for network applications in extreme thermal environments. For flexibility in very low-power applications, the
