GENERAL DESCRIPTION
The PCD3311C and PCD3312C are single-chip silicon
gate CMOS integrated circuits. They are intended
principally for use in telephone sets to provide the
dual-tone multi-frequency (DTMF) combinations required
for tone dialling systems. The various audio output
frequencies are generated from an on-chip 3.58 MHz
quartz crystal-controlled oscillator. A separate crystal is
used, and a separate microcontroller is required to control
the devices.
Both the devices can interface to I
2
C-bus compatible
microcontrollers for serial input. The PCD3311C can also
interface directly to all standard microcontrollers,
accepting a binary coded parallel input.
With their on-chip voltage reference the PCD3311C and
PCD3312C provide constant output amplitudes which are
independent of the operating supply voltage and ambient
temperature.
An on-chip filtering system assures a very low total
harmonic distortion in accordance with CEPT
recommendations.
In addition to the standard DTMF frequencies the devices
can also provide:
Twelve standard frequencies used in simplex modem
applications for data rates from 300 to 1200 bits per
second
Two octaves of musical scales in steps of semitones.
