LXT905

Intel® LXT905 Universal 10BASE-T Transceiver with 3.3 V Support Datasheet The Intel® LXT905 Universal 10BASE-T Transceiver is designed for IEEE 802.3 physical layer applications. It provides, in a single CMOS device, all of the active circuitry for interfacing most standard IEEE 802.3 controllers to 10BASE- T media. The LXT905 functions include the following: Manchester encoding/decoding Receiver squelch and transmit pulse shaping, Jabber Link integrity testing Reversed polarity detection/correction. The LXT905 drives the 10BASE-T twisted-pair cable, with only a simple isolation transformer, using a single 3.3 V or 5 V power supply. Integrated filters simplify the design work required for FCC-compliant EMI performance. The LXT905 is part of the Intel Carrier Class Ethernet family of products. The LXT905 Universal Transceiver offers 10BASE-T connectivity solutions that support operations over an extended temperature range, while providing features that increase reliability. The device has an operational lifetime of at least ten years, with less than 100 failures per billion hours, and is available a minimum of five years after the introduction of the product. Intel Carrier Class Ethernet products are ideal for applications where equipment must function reliably under environmentally controlled conditions, such as base stations, telecom/network switches, factory floor equipment, and industrial computers.
