e IC IC Features l Single-chip, 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 stability because the acoustic coupling between the speaker and microphone is much higher in speakerphones than in handsets where the coupling is mechanically suppressed. The CS6422 enables full-duplex conversation using echo cancellation and suppression in a single-chip solution. The CS6422 can easily replace existing half-duplex speakerphone ICs with a huge increase in conversation quality.
