UTC MC33218 LINEAR INTEGRATED CIRCUIT

VOICE SWITCHED

SPEAKERPHONE WITH

MICROPROCESSOR INTERFACE

DESCRIPTION

The UTC MC33218 voice switched speakerphone circuit

incorporates the necessary amplifiers, attenuators, level

detectors and control algorithm to form the heart of a high

quality hands-free speaker-phone system. Includes are a

microphone amplifier with mute, transmit and receive

attenuators a background monitoring system for both the

transmit and receive paths, and level detectors for each path.

An AGC system reduces the receive gain on long lines where

loop current and power are in short supply. A dial tone

detector prevents fading of dial tone. A chip disable pin

permits conserving power when the circuit is not in use.

Additionally, the UTC MC33218 has a serial data port

which permits microprocessor control of the receive volume

level, microphone mute, attenuator range, and selection of

transmit, receive, idle or normal modes. The data port can be

operated at up to 1.0MHz

SOP-24

DIP-24

The UTC MC33218 can be operated from a power supply,

or from the telephone line, requiring typically 4.6mA.It can be

used in conjunction with a variety of speech networks.

Applications include not only speakerphones, but intercoms

and other voice switched devices.

FEATURES

* Supply Voltage Range: 2.7V ~ 6.5V

* Attenuator Range: 53 or 27 dB (selectable)

* 2 Point Sensing with background oise monitor in each path

* Microprocessor port for control of:

Volume control(40dB range over 16 levels)

Mute microphone amplifier

Force to receive transmit, or idle modes

Attenuator range selection(27 or 53dB)
