Parallel Input Tone/pulse Dialer High-performance Silicon-gate Cmos Korea Corp.

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. By Kodenshi Korea Corp.
