CML Microcircuits (USA) Inc. Integrated Circuits (ICs) - Interface - Modems - ICs and Modules CMX865AD4-TR1K

The CMX865AD4-TR1K is a multi-standard modem designed for applications such as Wireless Local Loop, SMS phones, security systems, and industrial control systems. It supports various FSK standards including V.23, Bell 202, and V.21, with data rates of 300 bps to 1200 bps. The device features a low power consumption design while maintaining high performance, making it suitable for battery-operated devices. This modem integrates a DTMF decoder with low voice falsing and a standard DTMF encoder, allowing for the transmission and detection of user-specific tones and signals. It operates on a single supply voltage of 3.0V to 3.6V and is rated for a temperature range of -40¬8C to +85¬8C. The CMX865AD4-TR1K is available in 16-pin SOIC and TSSOP packages, requiring only passive external components for a complete line interface. The device also includes a high-speed serial bus for host control and data transfer, compatible with various microcontroller interfaces.
