Applications

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.
