CMX865AD4

Overview

The CMX865AD4 is a telecom signalling device from the CMX86X series, manufactured by CML Micro. It integrates DTMF encoding/decoding and FSK modem capabilities for V.23, V.21, Bell 103, and Bell 202 standards. The component operates on a single 3.0V to 3.6V supply with a typical operating current of 4 mA. It supports data rates up to 1200 bps and functions within a temperature range of -40°C to +85°C. The device features a serial interface and is housed in a 16-pin SOIC package.

Feature Summary

Integrates flexible line driver, hybrid, and receiver circuits requiring only passive external components.
Includes high-quality DTMF decoder with low voice falsing immunity and standard DTMF encoder.
Supports multi-standard FSK modulation for various telecommunications protocols.
Features a high-speed serial C-BUS interface compatible with microcontroller systems.

Applications

Wireless Local Loops
SMS Phones
Security Systems
Remote Utility Meter Reading
Industrial Control Systems

Procurement Notes

Verify the specific ordering suffix 'D4' corresponds to the 16-pin SOIC package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the procurement channel provides valid traceability for the component batch.

Selection Notes

Select this model for designs requiring integrated DTMF and FSK modem functionality in a compact form factor. The SOIC-16 package is suitable for surface mount assembly. Verify that the host system provides a compatible serial interface for C-BUS communication and meets the required voltage and temperature specifications.

Part Context

The CMX865AD4 belongs to the CMX86X family of telecom interface ICs. It serves as a combo device combining DTMF codec and modem functions. This specific part number denotes the SOIC package version, distinct from the TSSOP variant (CMX865AE4).

Replacement Considerations

The CMX865AE4 is a direct functional substitute offering identical electrical characteristics but utilizes a 16-TSSOP package instead of SOIC. Designers must verify footprint compatibility before substitution.
