PMR audio processor claims unrivalled performance
December 02, 2010 // Paul Buckley
CML Microcircuits has added a new audio scrambler and sub-audio signaling processor, the CMX148, to the company’s family of analog two way radio ICs. The device is intended for use in general leisure and professional PMR terminals in a worldwide market.
half-duplex device, the CMX148 utilises the host µC to perform signaling, including CTCSS/DCS encoding/decoding. Particularly suited to both the PMR markets and enhanced MURS/GMRS/FRS with GPS terminal designs, the IC features an FFSK/MSK data modem for packetised or free-format data operations. Features such as signal routing and filtering to assist host microcontroller based signaling encode/decode applications; a DTMF encoder/decoder and a full complement of auxiliary ADCs and DACs and dual synthesized clock outputs are available.
In addition, the signal processing blocks can be individually assigned to either of two signal-processing paths, which, in turn, can be routed from any of the three audio/discriminator input pins. This allows for a flexible routing architecture and permits different processing blocks to act on different analog inputs.
The EV1480 Evaluation Kit is designed to assist in the evaluation and application development of the CMX148 PMR Audio and Data Processor. The kit is in the form of a populated PCB comprising a CMX148 IC and appropriate supporting components and circuitry, incorporating all of the necessary power-supply regulation facilities for operation from a single 5-V supply.
The CMX148 operates on 3.3-V supply and includes selectable power-saving modes. It is available in 48-pin VQFN and LQFP packages.
