The LXT914 is an integrated multi-port repeater designed for mixed-media networks. It provides all the active circuitry required for the repeater function in a single CMOS device. It includes one Attachment Unit Interface (AUI) port and four 10BASE-T transceivers. The AUI port is mode selectable: DTE mode allows connection of an external transceiver (10BASE2, 10BASE5, 10BASE-T or FOIRL) or a drop cable. MAU mode creates a MAU output allowing direct connection to another DTE interface. The 10BASE-T transceivers are entirely self-contained.
