Solid State Supplies announced low power audio and data processor for PMR systems
The CMX148 PMR audio and data processor from CML Microsystems is now available exclusively in the UK from Solid State Supplies. The low power half-duplex audio, signalling and data processing IC provides maximum support to systems where the sub-audio signalling is managed within the microcontroller. The device features flexible power saving modes and its comprehensive audio processing facilities include complete audio-band processing, filtering, companding, pre or de-emphasis and frequency inversion scrambling.The CMX148 is suitable for general leisure and professional PMR terminals, particularly those with enhanced MURS/GMRS/FRS with GPS. It features an FFSK/MSK data modem for packetised or free-format data operations. Signal routing and filtering is included to assist host µC based signal encoding/decoding applications. A DTMF encoder/decoder, a full complement of auxiliary ADCs and DACs and dual synthesised clock outputs are included and the device is available in 48-pin VQFN and LQFP packages.
