LXT313/LXT316

Low Power E1 PCM Repeaters/Transceivers

General Description

The LXT313 and LXT316 are integrated repeater/

transceiver circuits for E1 carrier systems. The LXT313 is

a dual repeater/transceiver and the LXT316 is a single

repeater/transceiver. The LXT313 and LXT316 are

designed to operate as regenerative repeaters/transceivers

for 2.048 Mbps data rate PCM lines. Each includes all

circuits required for a regenerative repeater/transceiver

system including the equalization network, automatic line

build-out (ALBO), and a state-of-the-art analog/digital

clock extraction network tuned by an external crystal.

The key feature of the LXT313 family is that it requires

only a crystal and a minimum of other components to

complete a repeater/transceiver design. Compared with

traditional tuned coil-type repeaters/transceivers, they offer

significant savings in component and labor costs, along

with reduced voltage drop/power consumption, and

improved reliability. To ensure performance for all loop

lengths, the LXT313 and LXT316 are 100% AC/DC tested

using inputs generated by Level One’s proprietary

transmission line and network simulator.

The LXT313 and LXT316 are advanced CMOS devices

which require only a single 5-volt power supply.
