LXT318

E1 NTU/ISDN PRI Transceiver

Datasheet

The LXT318 is the first fully integrated transceiver for E1 Network Termination Unit (NTU) and

ISDN Primary Rate Interface (ISDN PRI) applications at 2.048 Mbps. The transceiver operates

from 0.0 km to 2.6 km of 0.6 mm (22 AWG) twisted-pair cable with no external components.

The LXT318 offers selectable HDB3 encoding/decoding, and unipolar or bipolar data I/O. The

LXT318 also provides jitter attenuation in either the transmit or receive direction starting at 3

Hz, and incorporates a serial interface (SIO) for microprocessor control.

The LXT318 offers a variety of diagnostic features including loopbacks and loss of signal

monitoring. It is built using an advanced double-poly, double-metal CMOS process and requires

only a single 5-volt power supply.

switchable to transmit or receive path

output

■ Exceeds ETSI TBR12/13 jitter transfer

■ Microprocessor controllable

■ Available in 28-pin DIP and PLCC

performance specifications

■ Fully restores the received signal after

transmission via a cable with attenuation of

43 dB @ 1024 kHz

■ Extended Temperature Range (-40° C to

+85° C)
