M-980-02
3V/5V General Purpose
Call Progress Tone Detector
INTEGRATED CIRCUITS DIVISION
Features Description
Covers the 315Hz to 640Hz Range (Common Call The M-980-02 is an integrated circuit tone detector for
Progress) general purpose use in automatic following of
Sensitivity to -38dBm switched telephone calls. The circuit uses low-power
Dynamic Range Over 38 dB CMOS techniques to provide the complete filtering
40ms Minimum Detect and control required for this function. The basic timing
8-Pin DIP or 16-Pin SOIC of the M-980-02 is designed to permit operation with
Single Supply CMOS (Low Power) almost any progress tone system.
Supply Range 2.8VDC to 5.5VDC
Inexpensive 3.58MHz Time Base The use of integrated circuit techniques allows the
Low Power Consumption (<15mW at 3V) M-980-02 to pack the complete frequency and
amplitude portion of call progress following into a
Applications
single 8- pin DIP or 16-pin SOIC. A 3.58 MHz
Automatic Dialers crystal-controlled time base guarantees accuracy and
Dialing Modems repeatability. 3V/5V operation increases customer
Traffic Measurement Equipment flexibility, improves reliability, and minimizes power
Test Equipment consumption.
