M-982-02

Precise Call Progress Tone Detector

Description

Features

• Precise detection of call progress tones

• Linear (analog) input

• Digital (CMOS compatible), tri-state outputs

• 22-pin DIP and 20-pin SOIC

• Single supply 3 to 5 volt (low power CMOS)

• Inexpensive 3.58 MHz crystal time base

• Wide dynamic range (30 dB)

• Lower power consumption (power-down mode)

• 425 Hz detection

The M-982-02 is an integrated circuit precise tone

detector for special-purpose use in automatic following

of switched telephone calls. The circuit uses low-

power CMOS techniques to provide the complete fil-

tering and control required for this function. The basic

timing of the M-982-02 is designed to permit operation

with almost any progress tone system.The use of inte-

grated circuit techniques allows the M-982-02 to pack

the five filters for call progress following into a single

22-pin DIP or 20-pin SOIC. A 3.58 MHz crystal-con-

trolled time base guarantees accuracy and repeatabil-

ity.

Applications

The M-982-02 is an enhanced drop-in replacement for

the M-982-01. It has a wider operating voltage range

(down to 3V). It has lower power consumption under

normal operating conditions. In addition, a power-

down (PD) feature is provided to further reduce power

consumption when inactive. It includes a 425 Hz

detector to support common international call progress

requirement.
