The codec bridges the gap between the audio world of microphones, earphones,
loudspeakers and the PCM digital world by providing a full PCM codec with all the
necessary transmit and receive filters.
Because the requirements for the codec correspond to the ARCOFI-SP PSB 2163 or
ARCOFI
characteristics are similar to those devices.
A block diagram of the codec is shown in figure 70.
The codec can be subdivided into three main blocks:
• Analog Front End (AFE)
• Digital Signal Processor (DSP)
• Codec Digital Interface (CDI)
A detailed description can be found in the following chapters.
