M-88L70

3V DTMF Receiver

Description

Features

The M-88L70 monolithic DTMF receiver offers small size,

low power consumption and high performance, with 3 volt

operation. Its architecture consists of a bandsplit filter

section, which separates the high and low group tones,

followed by a digital counting section which verifies the

frequency and duration of the received tones before

passing the corresponding code to the output bus.

• Operates between 2.7 and 3.6 volts

• Low power consumption

• Power-down mode

• Inhibit mode

• Central office quality and performance

• Inexpensive 3.58 MHz time base

• Adjustable acquisition and release times

• Dial tone suppression

• Functionally compatible with Clare’s M-8870

Figure 1 Pin Connections

The M-88L70 is a full DTMF Receiver that integrates

both bandsplit filter and decoder functions into a single

18-pin DIP or SOIC package. Manufactured using

CMOS process technology, the M-88L70 offers low

power consumption (18 mW max), precise data handling

and 3V operation. Its filter section uses switched capaci-

tor technology for both the high and low group filters and

for dial tone rejection. Its decoder uses digital counting

techniques to detect and decode all 16 DTMF tone pairs

into a 4-bit code. External component count is minimized

by provision of an on-chip differential input amplifier,

clock generator, and latched tri-state interface bus.

Minimal external components required include a low-cost

3.579545 MHz color burst crystal, a timing resistor, and a

timing capacitor.
