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.
