The CMX865A is a multi-standard modem for use in Wireless Local Loop, Short Message Service telephone based information and telemetry systems. Flexible line driver, hybrid and receiver circuits are integrated on chip, requiring only passive external components to build a 2 or 4-wire line interface.

A high-quality DTMF decoder with excellent immunity to falsing on voice and a standard DTMF encoder are included. Alternatively, these blocks can be used to transmit and detect user-specific, programmed single and dual-tone signals, simple melodies, call progress signals or modem calling and answering tones.

Host control and data transfer is via a high-speed serial bus that operates in normal and Powersave modes and which is compatible with most simple types of µC serial interface. An embedded USART allows multi-format asynchronous data and unformatted synchronous data to be received or transmitted as 8-bit bytes.

The CMX865A operates from a single 3.0V to 3.6V supply over a temperature range of -40°C to +85°C and is available in 16-pin SOIC (D4) and 16-pin TSSOP (E4) packages.
