New NXDN™ Processor with embedded Air Interface (AI) Protocol.

The CMX7131/7141 with the NXDN™ Function Image™ connects directly to the market-leading CMX994 Direct Conversion Receiver IC. Together these devices form a formidable chip-set, enabling a fast development cycle for small, highly-integrated, multi-standard capable digital radios that will exhibit a long battery life.

The majority of the NXDN™ air interface physical layer (layer 1) and data link layer (layer 2) is embedded in the NXDN™ Function Image™ plus a host of advanced features to support the complete radio system and simplify the overall radio design process.

NXDN™ is an FDMA digital Land Mobile Radio (LMR) open standard and has evolved to become a key narrowband technology in the LMR migration from analogue to digital. NXDN™ is supported by more than 25 international radio manufacturers and organisations that together form the NXDN™ Forum (www.nxdn-forum.com)

The new NXDN™ Function Image™ adds to the existing suite of CMX7131/7141 function images, now covering dPMR™, NXDN™, ARIB STD-T98, ARIB STD-T102 and legacy analogue PMR. A radio platform using the CMX7131/7141 can be switched to deliver any of these systems by uploading the appropriate Function Image™. This allows radio manufacturers to take advantage of economies-of-scale by adopting a Software Defined Radio (SDR) design route, with one radio design supporting a number of different systems and markets.

The DE9944 FDMA SDR Demonstrator is also available, providing the fastest route from development through to production.

The CMX7131/CMX7141 processors and function images are available now, offering low power 3.3V operation in small VQFN/LQFP packaging.
