CMX7262 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.
CMX7262 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 si
- 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 serial interface o Streaming input and output registers to streamline transfers and relax host service latenc
- Signal routing: o Choice of input sources
- C-BUS transfer from host, analogue audio input o Choice of output sources
