CMX673D4 Description

Short technical summary and product information.

The CMX673D4 from CML Microcircuits is a general-purpose call progress tone detector for Public Switched Telephone System (PSTN) applications. It utilizes advanced digital signal processing techniques to detect tones in the frequency band of 315Hz to 650Hz, distinguishing them from line noise or voice with low false detection rates.

 

This IC is capable of detecting single and dual tones, supporting worldwide tone compatibility. It operates with supply requirements between 2.7V and 5.5V, consuming a low current of 1.5mA and dissipating a maximum of 800mW. The CMX673D4 is designed for easy integration into a wide range of telecom equipment, including worldwide payphone systems, telephone redialling systems, dialling modems, banking and billing systems, and telecom test equipment.

 

The device is housed in a 16-SOIC package and is designed for surface mount applications. It operates across a temperature range of -40°C to 85°C. The CMX673D4 is pin-to-pin compatible with M980, TSC 75T980, and SSI980, offering a versatile solution for call progress monitoring.
