The CMX983 is an Analogue Front End (AFE) IC that bridges the gap between a digital radio’s RF section and the DSP/FPGA. Specifically designed to meet the needs of a Software Defined Radio (SDR), the CMX983 performs critical DSP-intensive functions, provides dual-channel analogue-to-digital and digital-to-analogue conversion, includes two RF fractional-N synthesisers and embeds a host of auxiliary ADCs and DACs for use within the radio system.
The CMX983 is suitable for radio systems employing modulation bandwidths up to 25.8kHz and is usable in satellite communication, high performance wireless data and professional two-way radio systems.
The CMX983 is highly configurable, supporting numerous sample rates and filtering characteristics. This configurability enables a high level of functionality, integration and connectivity with RF building block ICs. The CMX983 connects seamlessly with CML’s CMX994 Direct Conversion Receiver and the CMX998 Cartesian Feedback Loop Transmitter, to provide a complete small form factor, RF-to-digitised baseband solution.
