Fully Featured Digital Telephone Circuit With Embedded HDLC Transceiver And DSP For Tone Generations And Hands Free Operation

The MT9092 HPhone-II is a fully featured integrated digital telephone circuit which includes an HDLC data formatter. Voice band signals are converted to digital PCM and vice versa by a switched capacitor Filter Codec. The Filter Codec uses an ingenious differential architecture to achieve low noise operation over a wide dynamic range with a single 5 V supply. A Digital Signal Processor provides handsfree speaker-phone operation. The DSP is also used to generate Tones (DTMF, Ringer and Call Progress) and control Audio gains. Internal Registers are accessed through a serial microport conforming to INTEL MCS-51 specifications.
