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.
