Automatic tone burst mode

Call progress tone detection to -30dBm

The receiver section is based upon the industry

standard MT8870 DTMF receiver while the

transmitter utilizes

switched capacitor D/A

Applications

converter for low distortion, high accuracy DTMF

signalling. Internal counters provide a burst mode

such that tone bursts can be transmitted with precise

timing. A call progress filter can be selected allowing

a microprocessor to analyze call progress tones.

Personal computers

The MT8889C utilizes an adaptive micro interface,

which allows the device to be connected to a number

of popular microcontrollers with minimal external

logic. The MT8889C-1 is functionally identical to the

MT8889C except the receiver is enhanced to accept

lower level signals, and also has a specified low

signal rejection level.

Description

The MT8889C is a monolithic DTMF transceiver with

call progress filter.

It is fabricated in CMOS

technology offering low power consumption and high

reliability.
