... KS58006 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 in- dividual tone is digitally synthesized on the chip ...
