PBL 3726/18A

Universal Speech Circuit

Description

Key Features

PBL 3726/18A is a standard version of the PBL 3726 family of the mask-program-

mable, monolithic integrated speech circuits for use in electronic telephones.

It is designed for use with a low impedance microphone. Transmitting and receiv-

ing gain is regulated with line length. Different regulation for various current feeds

can be set by external resistors. Typical current feeds as 48 V, 2 x 200 ohm, 48 V

2 x 400 ohm and 48 V 2 x 800 ohm can be handled. Application dependent param-

eters such as line balance, side tone level, amplification and frequency response are

set by external components. Parameters are set independently which means easy

adoption for various market needs.

•

Minimum number of inexpensive

external components, 7 capacitors

and 11 resistors.

•

Mute function for operation with

DTMF-generator.

Transmit and receive gain regulation

for automatic loop loss compensa-

tion.

•

Extended current and voltage range

5 - 130 mA, down to 2 V.

Differential microphone input for

good balance to ground.

•

Balanced receiver output stage.

Short start-up time.

Stabilized DC-supply for low current

CMOS diallers and/or electret

microphones.

•

DTMF-input controlled by mute.
