LXT901A/907A - Universal Ethernet Transceiver Note - Not recommended for new designs

The LXT901A and LXT907A Universal Ethernet Transceivers are new-generation low power devices (3.3V operation) with improved noise immunity and output filtering. The feature set of the LXT901A/907A has been streamlined, removing Remote Signaling capabilities. The LXT901A and LXT907A provide all the active circuitry to interface most standard 802.3 controllers to either the 10BASE-T media or Attachment Unit Interface (AUI).
