L9312 Line Interface and Line Access Circuit

Forward Battery SLIC and Ringing Relay for TR-57 Applications

Description

Introduction

The L9312 electronic line interface and line access

circuit (LILAC) provides all the functions that are nec-

essary to interface a codec to the tip and ring of a

subscriber loop, integrating the battery feed and ring-

ing access relay in one low-power, low-cost package.

The Agere Systems Inc. L9312 is a combination full-

feature, ultralow-power SLIC, and solid-state ringing

access relay. It is part of a pin-for-pin compatible

family of devices designed to serve a wide variety of

applications. The L9312 is optimized for TR-57

access, forward battery only, applications.

The L9312 requires a 5 V and battery supply to oper-

ate. Included is an automatic battery switch. The

battery feed offers forward battery and on-hook

transmission. It also has a low-power scan and a dis-

connect mode.

Features

SLIC

In all operating states, this IC is designed for minimal

power dissipation. This device is designed to mini-

mize the number of external components required at

all interfaces.

■ 5 V and battery operation

■ Optional automatic battery switch

■ Four operational modes

The dc template, current limit, and overhead voltage

and loop supervision threshold are programmable via

an applied voltage source. The voltage source may

be an external programmable voltage source or

derived from the V^REFSLIC output.

■ Appropriate for 58 dB longitudinal balance applica-

tions

■ Minimal external components required at all inter-

faces

The integrated solid-state switch offers power ringing

access. Impulse noise is minimized, thus eliminating

the need for external zero-cross switching circuitry.

■ Ultralow power dissipation

■ Software/hardware adjustable dc parameters and

supervision thresholds

Solid-State Ring Relay

■ Low impulse noise

■ Current-limited switches/thermal protection

Applications

■ Pair Gain

■ Digital Loop Carrier (DLC)

■ Central Office (CO)

■ Fiber-in-the-Loop (FITL)
