CMX683D4 Description

Short technical summary and product information.

The CML Microcircuits CMX683D4 is a general-purpose Call Progress tone detector for monitoring call progress in Public Switched Telephone System (PSTN) applications. It can distinguish Dial Tone, Ringing, Busy, and Not Available states. The device utilizes advanced digital techniques for characterizing call progress tones, line noise, and voice signals, offering high sensitivity with low false detection rates.

 

Key features include detection of single and dual call progress tones, voice detect outputs (fast and slow), and a wide dynamic range with low falsing. It operates with a low power consumption of 600µA at 3.0V typical and requires a single 3.58MHz crystal for accurate performance. The supply voltage range is 2.7V to 5.5V.

 

The CMX683D4 is suitable for worldwide payphone systems, telephone redialling systems, dialling modems, banking and billing systems, telecom test equipment, and telecom security systems. It is available in a 16-SOIC package, designed for surface mount installation.

 

This IC is ideal for applications requiring reliable call progress monitoring and voice activity detection, enabling systems to commence charging or take other actions based on call status.
