KS58006 TONE/PULSE DIALER WITH REDIAL INTRODUCTION The KS58006 is DTMF/PULSE switchable dialer with a 32-digit redial which can be done using a slide switch. All necessary dual-tone frequencies are derived from a 3.579545 MHz TV crystal or ceramic resonator providing very high accuracy and stability. The required sinusoidal wave form for each individual tone is digitally synthesized on the chip. The generated wave form has very low total harmonic distortion (7% max). A voltage reference is gen.
