Universal 10BASE-T Transceiver with 3.3V Support

Datasheet

The LXT905 Universal 10BASE-T Transceiver is designed for IEEE 802.3 physical layer

applications. It provides, in a single CMOS device, all the active circuitry for interfacing most

standard IEEE 802.3 controllers to 10BASE- T media.

The LXT905 functions include Manchester encoding/decoding, receiver squelch and transmit

pulse shaping, jabber, link integrity testing, and reversed polarity detection/correction. The

LXT905 drives the 10BASE-T twisted-pair cable, with only a simple isolation transformer,

using a single 3.3V or 5V power supply. Integrated filters simplify the design work required for

FCC-compliant EMI performance.

The LXT905 is part of the Intel Carrier Class Ethernet family of products. The LXT905

Universal Transceiver offers 10BASE-T connectivity solutions that support operations over an

extended temperature range, while providing features that increase reliability. The device has an

operational lifetime of at least ten years, with less than 100 failures per billion hours, and will be

available a minimum of five years from the introduction of the product.

Intel Carrier Class Ethernet products are ideal for applications where equipment must function

reliably under environmentally controlled conditions, such as base stations, telecom/network

switches, factory floor equipment, and industrial computers.
