General Description

The PBL 3852 is an universal transmission circuit in bipolar technology that performs all the speech and line interface functions required to implement an electronic telephone set suitable for the majority of existing telephone network requirements.

Easy adaptation of the DC-mask to different line feed systems.

A summing point for auxiliary signals to be transmitted like DTMF and hands-free audio signal.

Overview

April3852 1996 PBL PBL 3852 Universal Transmission Circuit.

Key Features

Generates its own supply from the telephone line Adaptive to all types of telephone line feeding systems (i. e. 48V 2x200Ω, 60V 2x 600Ω, 48V 2x800Ω) Operates down to 2.1V (excl. polarity bridge) Adjustable DC-characteristic to the line Few inexpensive external components to function Easy adaptation for various market needs Dialler interface with DC-supply, mute, power -down and DTMF-input Confidence tone in the receiver at DTMF-dialling ”Soft clipping” that prevents distortion.
