These common platform processors enable a radio manufacturers to build a single platform radio that supports many different PMR standards.

With an embedded audio codec (ADC/DAC) the devices provide a complete baseband implementation with a  flexible interface to support both software and hardware implementations of the AMBE+2 Vocoder. A high level of advanced functionality is included that minimises both host interactions and host real-time control constraints. The CMX7241/CMX7341 PMR common platform processors can deliver FDMA digital PMR/LMR, 2-slot TDMA digital PMR/LMR and legacy analogue PMR/LMR. Based on the company’s FirmASIC® component technology, a Function Image™ is uploaded into the device to determine the overall functions and operating characteristics.

The PMR chipset comprises a low power RF direct conversion receiver (DCRx) IC (CMX994A/E) and a PMR common platform processor (CMX7341) with DMR/dPMR/NXDN/ARIB STD-T102/ARIB STD-T98 air interface coding and analogue PMR embedded within Function Images. The CMX994A/E and CMX7341 chipset enables a highly integrated, cost effective radio to be developed quickly with a low risk development route, for radio manufacturers planning to enter the Digital PMR market space.

Manufacturers preferring to evolve their current radio designs and not wishing to do a ground-up redesign can also take advantage of the CMX7241/CMX7341 benefits with their LD receiver capability.

The PMR chipset ICs are available in very small VQFN packages occupying a minimal PCB footprint and in conjunction with a suitable host microcontroller a small, highly integrated PMR radio can be realised.
