General Description
Most modern speakerphones use half-duplex operation,
which alternates transmission between the far-end talker
and the speakerphone user. This is done to ensure sta-
bility because the acoustic coupling between the
speaker and microphone is much higher in speaker-
phones than in handsets where the coupling is
mechanically suppressed.
The CS6422 enables full-duplex conversation using
echo cancellation and suppression in a single-chip solu-
tion. The CS6422 can easily replace existing half-duplex
speakerphone ICs with a huge increase in conversation
quality.
The CS6422 consists of telephone & audio interfaces,
two codecs and an echo-cancelling DSP.
