CML Microcircuits recently released a PMR common platform processor to support digital/analog FDMA PMR/LMR and two-slot TDMA digital systems. As engineers have moved two-way radio from analog to digital, a variety of digital FDMA and TDMA PMR/LMR systems have emerged along with the on-going requirement for a radio platform to support legacy analog. Each system potentially has different requirements and specs down to the radio architecture level. The CMX7241/7341 PMR Common Platform Processor addresses the issue.
The CMX7241/7341 provides a common platform that can deliver FDMA digital PMR/LMR, TDMA digital PMR/LMR and legacy analog. Based on CML’s FirmASIC component technology, a Function Image (FI) can be uploaded into the device to determine the CMX7241/7341’s overall functions and operating characteristics.
The first Function Image focuses on digital and analog 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, high-performance radio platform solution.
Important features:
- Automatic analog/digital detection
- Digital PMR/LMR (ETSI TS 102 658, TS 102 490 and EN 301 166 compliant; Embedded air interface physical and data link layers; and Mode 1, 2, and 3 operation)
- Analog PMR/LMR (EN 300 086, EN 300 296 and TIA-603-D compliant; Complete audio processing; Sub-audio signalling; Audio-band signalling; and MPT 1327 modem)
- Function Image roadmap includes DMR, NXDN and PDT
