CMX618 - RALCWI Vocoders

This page provides the datasheet information for the CMX618, a member of the CMX608 RALCWI Vocoders family.

Datasheet Summary

Description

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.

Features

  • Near Toll Quality RALCWI Coding Algorithm.
  • Multiple Bit Rate Modes:.
  • 2400 or 2750 bps.
  • 3600 bps with FEC Enabled.
  • 4-bit Viterbi Soft Decision Decoding.
  • Integrated Audio CODEC (CMX618/CMX638 only).
  • Integrated Input and Output Channel Filters.
  • 20ms, 40ms, 60ms and 80ms Packet Lengths.
  • No Licensing or Royalty Payments.
  • Ancillary Audio Functions:.
  • Voice Activity Detector.
  • Comfort Noise Generator.
  • DTMF and Single Tone Regeneration.
