Private mobile radio common platform processor
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. It 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 the company’s CMX994 direct conversion receiver IC it presents a flexible, highly integrated, small PCB footprint, high performance radio platform solution.
