LXT905

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 802.3 controllers to 10BASE- T media.

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.
