LXT915

( DataSheet : www.DataSheet4U.com ) LXT915 Simple Quad Ethernet Repeater Datasheet The LXT915 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 allows connection of an external transceiver (10BASE-2, 10BASE-5, 10BASE-T or FOIRL) or a drop cable. The 10BASE-T transceivers are entirely self-contained with internal filters that simplify the design work required for FCC-compliant EMI performance. An Inter-Repeater Backplane (IRB) interface allows 128 or more 10BASE-T ports to be cascaded, creating a large single-segment multi-port repeater. The LXT915 requires only a single 5-volt power supply due to its advanced CMOS fabrication process.
