DMR Chipset Solution

DMR Chipset Solution Provides a Fast Development Path to Entering the DMR Market.

Maldon, Essex - CML Microcircuits, a leading innovator and provider of low-power semiconductors for global wireless data and two-way radio communications markets, has released a DMR (Digital Mobile Radio) chipset solution.  The DMR chipset comprises a low power RF Direct Conversion Receiver (DCRx) IC (CMX994A) and a PMR Common Platform Processor (CMX7341) with the DMR Air Interface and coding embedded within a Function Image™.
The CMX994A and CMX7341 chipset along with DMR (7241/7341FI-2.x) Function Image™ enables a highly integrated radio to be developed quickly, cost effectively and providing a low risk development route for radio manufacturers planning to enter the DMR market space.

About the DMR Function Image
The 7241/7341FI-2.x Function Image™ implements much of the DMR Air Interface protocol including the physical layer 1 and data link layer 2 and is compliant with the ETSI TS 102 361 DMR standard. A high level of advanced functionality is included that minimises both host interactions and host real-time control constraints. The CMX7341 includes an embedded audio codec (ADC/DAC) with a flexible interface to support both software and hardware implementations of the AMBE+2 Vocoder.

About the RF Receiver IC
The CMX994A is CML’s new Direct Conversion Receiver IC.  The device PowerTrade™ feature provides a flexible power control facility to optimise current consumption in normal and stand-by operating modes. CMX994A connects directly to the CMX7341 PMR Common Platform Processor with the DMR Function Image™ automatically setting up and managing the RF section.
The DMR 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 DMR radio can be realised.

About the CMX7241/7341
The CMX7241/CMX7341 PMR Common Platform Processor can deliver FDMA digital PMR/LMR, 2-slot TDMA digital PMR/LMR and legacy analogue. Based on CML's proprietary component technology, a Function Image™ can be uploaded into the device to determine the overall functions and operating characteristics.
