w w w .D a S a t . U LXT901/907 4 t e 10BASE-T and AUI Transceivers Universal e h m o c Datasheet The LXT901 and LXT907 Universal 10BASE-T and AUI Transceivers are designed for IEEE 802.3 physical layer applications. They provide 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, they also support full-duplex operation at 20 Mbps. The LXT901 and LXT907 are identical except for the function of one pin. The LXT901 offers selectable termination impedance to allow the use of either shielded or unshielded twisted-pair cable. The LXT907 offers a signal quality error (SQE) disable function. Common LXT901 and LXT907 functions include Manchester encoding/decoding, receiver squelch and transmit pulse shaping, jabber, link testing and reversed polarity detection/ correction. Integrated filters simplify the design work required for FCC-compliant EMI performance.
