Intel LXT908 Universal 3.3 V 10BASE-T
and AUI Transceiver
Datasheet
The LXT908 Universal 10BASE-T and AUI Transceiver (call hereafter LXT908 Transceiver) is
designed for IEEE 802.3 physical layer applications. It provides all the active circuitry to
interface most standard 802.3 controllers to either the 10BASE-T media or Attachment Unit
Interface (AUI). In addition to standard 10 Mbps Ethernet, the LXT908 Transceiver also
supports full-duplex operation at 20 Mbps.
LXT908 Transceiver functions include Manchester encoding/decoding, receiver squelch and
transmit pulse shaping, jabber, link testing and reversed polarity detection/correction. The
LXT908 Transceiver can be used to drive either the AUI drop cable or the 10BASE-T twisted-
pair cable with only a simple isolation transformer. Integrated filters simplify the design work
required for FCC-compliant EMI performance.
The LXT908 Transceiver is fabricated with an advanced CMOS process and requires only a
single 3.3V power supply.
