Description

i) Speakerphone switching algorithm

ii) DTMF and single tone generator

iii) Tone Ringer

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

5V 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. The device is
