CMX608 Datasheet (Consumer Microcircuits Limited)

CMX608, RALCWI Vocoders

The CMX608/CMX618/CMX638 are flexible, high integration, high performance, RALCWI (Robust Advanced Low Complexity Waveform Interpolation) Vocoders, offering near toll quality voice at very low bit rates.

A Forward Error Correction (FEC) engine provides optimum performance in real life applications.
