General Description

The M-984-02 Special Information Tone Detector is a monolithic integrated circuit designed to provide reliable detection of many common telephone network status signals.

In particular, it detects the signals known as Special Information Tones (SITs) or error tones as defined by the CCITT, and single tones often used as dial tone, audible ringing, and other general progress indications.

The M-984-02 uses CMOS switched capacitor filters and a crystal time base to achieve the high stability and accuracy specified.

Overview

M-984-02 Special Information Tone Detector.

Key Features

  • Detects single-frequency tones used for error indication and call progress in telephone systems.
  • Provides detection windows for: 400/425 Hz (Call Progress) 950 Hz (Special and error indication) 1400 Hz (Special and error indication) 1800 Hz (Special and error indication).
  • Separate tri-state outputs for each tone window.
  • Inexpensive 3.58 MHz crystal time base.
  • Auxiliary 3.58 MHz clock output.
  • 14-pin DIP package and 16-pin SOIC package.
