Description
The M-980-02 is an integrated circuit tone detector for
general 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 DIP or 16-pin SOIC. A 3.58 MHz crystal-controlled
time base guarantees accuracy and repeatability.
3V/5V operation increases customer flexibility,
improves reliability, and minimizes power consump-
tion.
