The IN91531N provides a 4-bit data input and a handshaking signal to serve as
microcomputer interfaces. Under microcomputer control the IN91531N generates both a
DTMF signal and a pulse output for telephone dialing.
All necessary dual-tone frequencies and dial pulse
outputs are derived from the widely used TV crystal
standard, providing high accuracy and stability. The
required sinusoidal waveform for individual tones is
digitally synthesized on the chip, resulting in a
waveform with very low total harmonic distortion.
