The CMX188 ACE Processor from CML Microcircuits is designed to provide the digital advantage to analog two-way radios and walkie-talkies, serving both licence-free and licensed two-way radio market sectors. The CMX188 combines an embedded low-bit-rate vocoder, audio-band modem, and digital voice features.

The plug and play solution provided by the CMX188 ACE Processor provides a new approach by enabling digital voice features and functionality not normally found on analog two-way radio. These include: secure digital voice encryption, digital voice storage/retrieval including step back feature, instant voice capture to eliminate PTT clipping, auto-adaptive VOX and packet data.

Built into the CMX188 is CML’s proven and reliable RALCWI (Robust Advanced Low Complexity Waveform Interpolation) vocoder providing near toll quality speech at a low bit-rate. Noise gating is included in the Vocoder function, in both transmit and receive operations to minimize the effects of background noise and improve the overall voice quality.

The CMX188 is a plug-and-play device built on CML’s FirmASIC technology and is available in small 48-pin VQFN and LQFP packages.
