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.
