LXT908
Universal 3.3V 10BASE-T and AUI Transceiver
Datasheet
The LXT908 Universal 10BASE-T and AUI 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 also supports full-duplex operation at 20 Mbps.
LXT908 functions include Manchester encoding/decoding, receiver squelch and transmit pulse
shaping, jabber, link testing and reversed polarity detection/correction. The LXT908 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 is fabricated with an advanced CMOS process and requires only a single 3.3V
power supply.
