M-8870 DTMF Receiver

•

Low power consumption

Adjustable acquisition and release times

Central office quality and performance

Power-down and inhibit modes (-02 only)

Inexpensive 3.58 MHz time base

Single 5 volt power supply

Dial tone suppression

Applications include: telephone switch equipment, re-

mote data entry, paging systems, personal computers,

credit card systems

The M-8870 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 technol-

ogy, the M-8870 offers low power consumption (35 mW max)

and precise data handling. Its filter section uses switched ca-

pacitor 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 in-

clude a low-cost 3.579545 MHz color burst crystal, a timing re-

sistor, and a timing capacitor.

Figure 1 Pin Connections

The M-8870-02 provides a “power-down” option which, when

enabled, drops consumption to less than 0.5 mW. The

M-8870-02 can also inhibit the decoding of fourth column digits

(see Table 5).
