Manufacturer: Consumer Microcircuits Limited

Overview: CML Microcircuits MUNICATION SEMICONDUCTORS CMX608/CMX618/ CMX638 RALCWI Vocoders D/608_18_38/11 September.

General Description

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: Voice Encoder, FEC Encoder, Voice Decoder and FEC Decoder.

Key Features

  • Near Toll Quality RALCWI Coding Algorithm.
  • Multiple Bit Rate Modes:.
  • 2400 or 2750 bps.
