Overview
March 1996 PBL 3726/18A Universal Speech Circuit Description PBL 3726/18A is a standard version of the PBL 3726 family of the mask-programmable, monolithic integrated speech circuits for use in electronic telephones.
It is designed for use with a low impedance microphone.
Transmitting and receiving 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 parameters such as line balance, side tone level, amplification and frequency response are set by external components.
Parameters are set independently which mea...
