Working Principle

The 501HCA27M0000DAFR oscillator operates based on the negative resistance principle. Negative resistance is a phenomenon that occurs in certain nonlinear circuits where the voltage across certain components is inversely proportional to the current flowing through them. In other words, when the current through the component increases, the voltage across it decreases, and vice versa. The oscillator utilizes this phenomenon to generate an output waveform.

The working of the oscillator is as follows. First, a sinusoidal current is applied to the input which is converted into an AC voltage through the rectifier circuit. This voltage is used to charge the capacitor via a diode. When the voltage across the capacitor reaches a certain level, the current flows through the diode and the resistor. This triggers the oscillation cycle. As the voltage across the resistor is lower than the voltage across the capacitor, the current flows in the opposite direction and the oscillation cycle repeats itself.

The output waveform produced by the 501HCA27M0000DAFR oscillator is a square wave with adjustable frequency and amplitude. The oscillator also provides excellent temperature stability and low jitter performance. It is capable of operating even in extreme temperature conditions and can be operated up to 85°C.

The 501HCA27M0000DAFR oscillator is a highly reliable and robust device which is used for various low drift control applications. Its excellent temperature stability, low jitter performance, and adjustable frequency and amplitude make it an ideal choice for applications such as automotive electronics, aerospace, and military.
