Precise Call Progress And Special Information Tone Generator

The M-985-01 is an integrated circuit precise Tone detector for call progress and special information Tones (SIT), as defined by CCITT. The use of integrated circuit techniques allows the M-985-01 to pack the eight Filters for call progress detection into a single 22-pin DIP or a 20-pin SOIC. A 3.58 MHz crystal-controlled time base guarantees accuracy and repeatability. The M-985-01 combines the call progress detection of the M-982-02 and the SIT detection of the M-984-02. It has an operating voltage range down to 3V. It has low power consumption under normal operating con- ditions. A power down (PD) feature is provided to fur- ther reduce power consumption when inactive. By Clare, Inc.
