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.
