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