The
KK
91531 provides a 4-bit data input and a handshaking signal to
serve as microcomputer interfaces. Under microcomputer control the
KK
91531 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.
4-bit parallel data input from microcomputer
TTL compatible inputs and outputs
Uses TV crystal standard (3.58 MHz) to derive all frequencies,
providing high accuracy and stability
