CML Microcircuits, a provider of low-power semiconductor solutions for wireless data and two-way radio communications markets, has further enhanced the function image suite of its CMX7241/CMX7341 PMR common platform processors to cover most professional mobile radio (PMR) systems.
All major PMR systems are now supported including: DMR, dPMR, NXDN, ARIB STD-T102, ARIB STD-T98 and legacy analogue PMR, all with automatic digital/analogue detection. The CMX7241/CMX7341 PMR common platform processors now provide great flexibility and enable a radio manufacturer to build a single platform radio capable of supporting many different PMR standards.
The CMX7241/CMX7341 PMR Common Platform Processor
With an embedded audio codec (ADC/DAC) the devices provide a complete baseband solution with a flexible interface to support both software and hardware implementations of the AMBE+2 Vocoder.
A high level of advanced functionality is included, which 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 CML's FirmASIC component technology, a function image is uploaded into the device to determine the overall functions and operating characteristics.
PMR chipset provides fast path to DMR market
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.
I/Q and limiter discriminator receiver supported
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.
