CMX638 Overview
The CMX608/CMX618/CMX638 are flexible, high integration, high performance, RALCWI (Robust Advanced Low plexity 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. The RALCWI Vocoder prises four independent functions which are selectable by the host:.
