monolithic DTMF receiver; 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

microprocessor bus is provided and is directly

compatible with 6800 series microprocessors. The

MT8880C-1 is functionally identical to the MT8880C

except for the performance of the receiver section,

which is enhanced to accept and reject lower signal

levels.

Description

The MT8880C/C-1 is a monolithic DTMF transceiver

with call progress filter. It is fabricated in Mitel’s

ISO -CMOS technology, which provides low power

dissipation and high reliability. The DTMF receiver is
