www.DataSheet4U.com CS6422 CS6422 Enhan ced Enhanced Full-Duplex Full-duplex Sp eakerphone Speakerphone IC IC Features l Single-chip, General Description Mos t modern speakerphones use half-duplex operation, which alternates transmissio n between the far-end talker and the sp eakerphone user. This is done to ensure stability because the acoustic couplin g between the speaker and mi

crophone is much higher in speakerphones than in handsets where the coupling is mechanically suppressed. The CS6422 en ables full-duplex conversation using ec ho cancellation and suppression in a si ngle-chip solution. The CS6422 can easi ly replace existing half-duplex speaker phone ICs with a huge increase in conve rsation quality. The CS6422 consists of telephone & audio interface
