New wideband mode added to the CMX983 AFE with RF Frac-N Synths
Maldon, Essex – CML Microcircuits, a leading innovator and provider of low-power semiconductor solutions for global wireless digital voice and data communications markets, has added a wideband operating mode to its popular Analogue Front End (AFE) IC that also incorporates two RF Frac-N synthesisers.
The CMX983 AFE IC 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 2.1GHz fractional-N synthesisers, and embeds a host of auxiliary ADCs and DACs for use within the radio system.
The CMX983 new wideband mode caters for modulation bandwidths up to 50kHz, and it is especially suited to satellite communication, high performance wireless data and professional two-way radio systems. It is highly configurable and supports 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.
The CMX983 is available in a small 64-lead VQFN package.
