PBL 385 71

High current Speech and

Line interface Circuit

Key features.

Description.

•

Minimum number of external

components, 5 capacitors and 10

resistors.

Easy adaption to various market

needs.

PBL 38571 is a monolithic integrated speech transmission circuit for use in

electronic telephones and as DECT line interface with balanced in - and output. It is

designed to accomodate either a low impedance dynamic microphone or an electret

microphone that can be supplied from the circuits own DC - supply. A signal summing

point at the transmitter input is available. An internally preset line length

compensation can be adjusted with external resistors to fit into different current feed

systems as for ex. 48 V, 2 x 200 ohms, 48 V, 2 x 400 ohms and 48 V, 2 x 800

ohms.The line regulation can be shut off in low mode. Application dependent para-

meters such as line balance, side tone level, transmitter and receiver gains and

frequency responces are set independently by external components which means an

easy adaption to various market needs. The setting of the parameters, if carried out in

certain order will counteract the interaction between the settings. It features high line

current capability on a small footprint. Function compatible with the PBL 3781 family

of speech circuits.

•

Mute control input for operation with

DTMF - generator.

Transmitter and receiver gain

regulation for automatic loop loss

compensation. Disconnectable.

Extended current and voltage range

5 - 130 mA, down to 2 V.

Differential microphone input for

good balance to ground.

Balanced receiver output stage.

In 16 - pin DIP and SO BW batwing

packages.

•

Short start up time.

Excellent RFI performance.
