Repeater

Datasheet

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.

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 Repeater requires only a single 5-volt power supply due to an advanced CMOS

fabrication process.

Product Features

■ Four integrated 10BASE-T transceivers

■ Synchronous or asynchronous inter-

repeater backplane supports “hot

swapping”

■ Inter-repeater backplane allows cascaded

repeaters, linking 128 or more 10BASE-T

ports

and one AUI transceiver on a single chip

■ Programmable DTE/MAU interface on

AUI port

■ Seven integrated LED drivers with four

unique operational modes

■ Serial port for selecting programmable

■ On-chip transmit and receive filtering

options

■ Automatic partitioning of faulty ports,

■ 68-pin PLCC (Commercial or Extended

enabled on an individual port basis

temp range)

■ Automatic polarity detection and correction

■ 100-pin PQFP (Commercial temp range)

■ Programmable squelch level allows

extended range in low-noise environments

Applications

■ LAN Repeaters

■ Switched Repeater Clusters

■ Integrated Repeaters
