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.  
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
