Description
The MT8888C is a monolithic DTMF transceiver with
call progress filter. It is fabricated in CMOS technology
offering low power consumption and high reliability.
The receiver section is based upon the industry
standard MT8870 DTMF receiver while the transmitter
utilizes a switched capacitor D/A 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.
The MT8888C utilizes an Intel micro interface, which
allows the device to be connected to a number of
popular microcontrollers with minimal external logic.
