CMX683 - Call Progress and Voice Detector

This page provides the datasheet information for the CMX683, a member of the CMX683-CML Call Progress and Voice Detector family.

Description

The CMX683 is a general purpose Call Progress tone detector for use in monitoring the progress of calls in Public Switched Telephone System (PSTN) applications.

Dial Tone, Ringing, Busy and Not Available states can be distinguished by using the host µC to qualify the cadence of the CP DETECT output.

Features

  • Detects Single and Dual Call Progress Tones.
  • Worldwide Call Progress Tone Compatibility.
  • "Voice" Detect Outputs (Fast and Slow).
  • Wide Dynamic Range with Low Falsing.
  • Low Power Operation: 600µA at 3.0V typ.
  • 3.58MHz Xtal/Clock Oscillator CMX683 Call Progress and "Voice" Detector Provisional Issue.
