CMX683E4 Description

Short technical summary and product information.

The CML Microcircuits CMX683E4 is a versatile Call Progress and Voice Detector IC designed for monitoring telephone call progress in Public Switched Telephone System (PSTN) applications. It can distinguish between Dial Tone, Ringing, Busy, and Not Available states.

 

This device utilizes advanced digital techniques for characterizing call progress tones, line noise, and voice signals, offering high sensitivity with low false detection rates. It supports various call progress systems, including the 'stuttered dial tone' found in voicemail systems. Separate outputs provide voice activity detection over short and long periods, useful for billing systems.

 

The CMX683E4 operates with a supply voltage range of 2.7V to 5.5V and features low power consumption, typically 600µA at 3.0V. It includes a 3.58MHz crystal oscillator for accurate performance. The IC is housed in a 16-TSSOP package and is designed for surface mount installation.

 

Applications for the CMX683E4 include worldwide payphone systems, telephone redialing systems, dialling modems, banking and billing systems, telecom test equipment, and telecom security systems.
