Platform processor will support digital/analogue FDMA PMR/LMR and 2-slot TDMA digital two-way radio systems

CML Microcircuits unveils PMR common platform processor

CML Microcircuits has released a PMR common platform processor to support digital/analogue FDMA PMR/LMR and 2-slot TDMA digital systems.

During the migration of Two-way Radio from analogue to digital, a number of digital FDMA and TDMA PMR/LMR systems have emerged along with the on-going requirement for a radio platform to support legacy analogue.

With each system potentially having different requirements and specification down to radio architecture level, the radio manufacturers' goal of a single cost-effective radio platform to fit all has become complex.

The CMX7241/7341 PMR common platform processor sets out to address this. The CMX7241/7341 provides a common platform that can deliver FDMA digital PMR/LMR, TDMA digital PMR/LMR and legacy analogue.

Based on CML's proprietary FirmASIC component technology, a Function Image (FI) can be uploaded into the device to determine the CMX7241/7341 overall functions and operating characteristics.

The first function image focuses on digital and analogue FDMA PMR/LMR. It provides a comprehensive feature set including auxiliary functions to support the whole radio. When combined with CML's CMX994 direct conversion receiver IC it presents a flexible, highly integrated, small PCB footprint, high performance radio platform solution.

Main Features:
• Automatic analogue/digital detection
• Digital PMR/LMR
• ETSI TS 102 658, TS 102 490 and EN 301 166 compliant

• Analogue PMR/LMR
• EN 300 086, EN 300 296 and TIA-603-D compliant
• Complete audio processing
• Sub-audio signalling
• Audio-band signalling
• MPT 1327 modem
• Function image roadmap includes: DMR, NXDN and PDT.
