Hot-selling and scarce LXT908PE Universal 3.3V 10BASE-T and AUI Transceiver PLCC spot stock

Product Descriptions

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.
