CS6422 EEnnhhaanncceeddFFuulll--Dduupplleexx SSppeeaakkeerrpphhoonnee IICC l Single-chip, full-duplex, hands-free operation l Optional Tx Noise Guard l Programmable attenuation during double-talk l Optional 34 dB microphone preamplifier l Dual channel AGC’ed volume controls with mute l Dual integrated 80 dB IDR codecs l Speech-trained Network and Acoustic Echo Cancellers l Rx and Tx supplementary echo suppression l Configurable half-duplex training mode l Powerdown mode l Microcontroller Interface 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. The CS6422 consists of telephone & audio interfaces, two codecs and an echo-cancelling DSP.
