Intel® LXT914 Flexible Quad Ethernet Repeater
The Intel® LXT914 Flexible Quad Ethernet Repeater (called hereafter the LXT914 Repeater) 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 with internal filters which simplify the design work required for FCC-compliant EMI performance.
Features
• Four integrated 10BASE-T transceivers and one AUI transceiver on a single chip
• Programmable DTE/MAU interface on AUI port
• Seven integrated LED drivers with four unique operational modes
• On-chip transmit and receive filtering
• Automatic partitioning of faulty ports, enabled on an individual port basis
• Automatic polarity detection and correction
• Programmable squelch level allows extended range in low-noise environments
• Synchronous or asynchronous interrepeater backplane supports “hot swapping”
• Inter-repeater backplane allows cascaded repeaters, linking 128 or more 10BASE-T ports
• Serial port for selecting programmable options
• 68-pin PLCC (Commercial or Extended temp range)
• 100-pin PQFP (Commercial temp range)Applications
• LAN Repeaters
• Integrated Repeaters
• Switched Repeater Clusters
