M-980-02

3V/5V General Purpose Call Progress Tone Detector

Features Description • Covers the 315 to 640 Hz range (common callprogress) The M-980-02 is an integrated circuit tone detector forgeneral purpose use in automatic following of switched telephone calls. The circuit uses low-power CMOS techniques to provide the complete filtering and control required for this function. The basic timing of the M- 980-02 is designed to permit operation with almost any progress tone system.The use of integrated circuit techniques allows the M-980-02 to pack the complete frequency and ampli- tude portion of call progress following into a single 8- pin DIPor 16-pin SOIC. A3.58 MHz crystal-controlled time base guarantees accuracy and repeatability. 3V/5V operation increases customer flexibility, improves reliability, and minimizes power consump- tion. ?
