Key Features

Description

•

Low cost

The PBL 3766 Subscriber Line Interface Circuit (SLIC) is a monolithic integrated

circuit, manufactured in 75 V bipolar technology. The PBL 3766 SLIC facilitates the

design of cost effective, high performance on-premises (ONS) analog line interface

cards for PABX systems and terminal adapters. Small package size and few

required external components result in a miniaturized design.

The PBL 3766 programmable, constant current loop feed system can operate with

battery supply voltages between -24 V and -58 V.

The SLIC incorporates loop current and ring trip detection functions as well as a

ring relay driver.

The two- to four-wire and four- to two-wire voice frequency (vf) signal conversion,

i.e. the hybrid function, is provided by the SLIC in conjunction with either a conven-

tional or a programmable CODEC/filter.

Few external components

Programmable, constant current loop

•

Line feed characteristics independent

of battery supply variations

-24 V to -58 V battery supply voltage

range

Detectors

– programmable loop current detector

– ring trip detector

The PBL 3766 package is a 22 pin, plastic dual-in-line (batwing) or a 28-pin, plastic

j-leaded chip carrier (PLCC).

The differences between PBL 3766 and PBL 3766/6 are the specifications for

balance, output offset voltage, and insertion loss.
