The MT8992, MT8993, MT8993B is an intergrated digital telephone circuit which provides an on-chip HDLC data formatter(H-Phone). Conversion of analog signals to digital PCM and vice versa is accomplished with an on-chip filter codec. Digital signal processing techniques provide speakerphone operation and generation of ringing tone and DTMF signals.
