Multi Standard Feature Phone Integrated Circuit

Description

The U3810BM multi-standard feature phone circuit is

designed to be used with a microcontroller using a 2-wire

serial bus. It performs all speech and line interface

functions required in an electronic telephone set: the

ringing function with switching regulator and melody

generator, the DTMF dialling, the loudhearing with

antilarsen and antidistortion systems, a power supply, a

clock and a reset for the microcontroller. Transmit, receive

and loudhearing gains control / AGC range / DTMF

frequencies, pre-emphasis and level / melody generator,

and mutes are programmable through the serial bus.
