Description

The CD22859 is a CMOS dual-tone multifrequency (DTMF)
tone generator for use in dual-tone telephone dialing
systems. The device can easily be interfaced to a standard
push-button telephone keyboard to provide enabling
operation directly with the telephone lines.
The CD22859 generates standard DTMF sinusoidal dialing
tones from an on-chip reference crystal oscillator. The
reference oscillator uses an inexpensive 3.579545MHz color
TV crystal to create highly stable and accurate tones. The
sinusoidal tones are digitally synthesized by a stair-step
approximation.
