CMX7262 Datasheet Twelp Vocoder

Manufacturer: Consumer Microcircuits Limited

Overview: CML Microcircuits MUNICATION SEMICONDUCTORS CMX7262 TWELP Vocoder D/7262_FI-1.x/4 August 2013 DATASHEET Advance Information 7262 FI-1.

General Description

The CMX7262 TWELP Vocoder IC is a device supporting a Tri-Wave Excited Linear Prediction (TWELP) vocoder functionality in a single chip.

The CMX7262 is capable of encoding analogue voice into TWELPencoded frames.

It is capable of decoding TWELP-encoded frames back to analogue voice.

Key Features

  • High-performance, low bit rate vocoder using TWELP (Tri-wave Excited Linear Prediction) technology.
  • Crystal clear voice and excellent performance in real-life radio operation.
  • Excellent performance providing naturalsounding speech and high quality non-voiced signals such as emergency services sirens.
  • Half-duplex operation.
  • FEC built in to each vocoder frame.
  • Noise Reduction.
  • Integral voiceband audio codec (No external DSP or codecs required).
  • C-BUS host s.
