Oscillators

An oscillator is an electronic circuit which generates a repeating electrical signal, usually a sine wave, square wave or a pulse wave. Oscillators are used in a wide range of applications, from being used as clock generators in digital electronics circuits to being used as power drivers of piezoelectric elements in ultrasonic cleaners. One such oscillator is the 591AC150M000DG.

591AC150M000DG Application Field

The 591AC150M000DG is a high stability, low power, CMOS oscillator that is commonly used in the fields of aviation, automotive, and industrial applications. It is usually used in systems requiring extreme temperature regulation and stringent timing accuracy such as military systems and high-end consumer electronics.

591AC150M000DG Working Principle

At the core, the 591AC150M000DG is an astable multivibrator, which is essentially two amplifying devices cross-coupled to form two complementary outputs. The first device amplifies the signal from the second device while the second device amplifies the signal from the first, resulting in a feedback circuit that oscillates. In the 591AC150M000DG, this astable multivibrator is powered by an external clock input.

The clock input is padded with an internal voltage regulator that adjusts the supply voltage to match the oscillator\'s input requirement. The external clock frequency is then divided into two opposite phases, which results in two complementary sine wave outputs of equal frequency and phase. The two outputs then drive complementary CMOS output stages to generate a clean sine wave signal.
