Description
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
fabricated in
Mitel's
low
technology.
