Description
The M-991 is a call progress tone generator integrated
circuit for use in telephone systems. The circuit uses
low-power CMOS techniques to generate tones which
are digitally controlled and highly linear. The M-991 is
designed to permit operation with almost any system.
The use of integrated circuit techniques allows the M-
991 to incorporate the control, tone generating, and
power output buffer into a single 14-pin DIP or a 16-pin
SOIC. A 3.58-MHz (color burst) crystal-controlled time
base guarantees accuracy and repeatability.
