TECHNICAL DATA
PARALLEL INPUT TONE/PULSE DIALER
High-Performance Silicon-Gate CMOS
The
KK91531
provides a 4-bit data input and a handshaking signal to
serve as microcomputer interfaces. Under microcomputer control the
KK91531
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.
