Universal Speech Circuit

Key Features

Description

•

Low own current consumption

The PBL 3853 is a biopolar integrated speech circuit with specific parameters making

it highly suitable to be used as a line interface and speech circuit in a telephone line

powered electronic payphone. Emphasis has been put on low current consumption in

the IC thus facilitating that a greater part of the available line current can be used to

power other electrical functions in the design. From a minimum line current of

16 mA, 12 mA at 4.5 V can be used to power auxiliary functions. The circuit can

optionally create an active impedance towards the telephone line, set by external

passive components, to reduce the current consumption for the transmitted signal.

The circuit is designed to be used with a low impedance dynamic microphone but can

be used with an electret type as well. The receiver drives a low ohm dynamic

transducer directly. External clamping diodes are required on the receiver output.

Both transmitter and receiver can be muted separately (receiver cut off). Line length

regulation of the gain is possible in both receiver and transmitter. It is also possible to

use the circuit without regulation. Payphone tones and confidence tone in the recei-

ver at DTMF dialling can be injected directly into the receiver amplifier where their

levels are not affected by line length regulation and without the signal going out on

the line. All pin numbers refer to DIP package unless otherwise noted.

Can operate both with active and

passive impedance towards the line
