Overview

PBL 385 41 November 1998 PBL 385 41 Universal Speech Circuit Description.
PBL 38541 is a monolithic integrated speech transmission circuit for use in electronic telephones or in any other line interface application.
High settable supply current for auxiliary functions, up to 6.
0 mA (at high line currents).
The circuit is designed to accomodate either a low impedance dynamic or an electret microphone.
Microphone can be muted separately.
Payphone signaling and DTMF dialling tones have a separate input that is controlled by a mute signal.
A signal summing point is available at the transmitter input.
An internally preset line length compensation can be adjusted with external resistors to fit i...
