M-991

Call Progress Tone Generator

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.
