CML’s new CMX865A DTMF codec and telecom signalling combo gives designers increased flexibility when designing new-generation telemetry and telephone based information systems.
The low-cost IC offers advanced performance and low power requirements in a small footprint package, making it ideal for wireless local terminals (FCT/FWT/WLL), private branch exchanges (PBXs) and alarm and monitoring applications.
The CMX865A offers multistandard signalling capabilities, with data applications being facilitated by a flexible V.23/V.21 FSK (plus Bell equivalent) on-chip modem. Flexible line driver, hybrid and receiver circuits are integrated on-chip, requiring only passive components to build a 2- or 4-wire line interface. A high-quality DTMF decoder offers excellent immunity to noise on voice and a standard DTMF encoder is included to expand the range of suitable applications. Host control and data transfer are via a high-speed serial bus that operates in normal and power-save modes, compatible with most simple types of microcontroller serial interface. An embedded USART allows multiformat asynchronous data and unformatted synchronous data to be received or transmitted as 8-bit bytes.
The CMX865A operates from a single 3,0 V to 3,6 V supply over a temperature range of -40°C to +85°C and is available in 16-pin SOIC (D4) or 16-pin TSSOP (E4) packages.
