LXT914
Flexible Quad Ethernet Repeater
Datasheet
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 with internal filters which simplify the design work required for FCC-compliant EMI
performance.
An inter-repeater backplane interface allows 128 or more 10BASE-T ports to be cascaded
together. In addition, a serial port provides information for network management.
The LXT914 requires only a single 5-volt power supply due to an advanced CMOS fabrication
process.
