Working Principle

The OH300-50503CF-012.8M oscillator can be regarded as a combination of resistors and capacitors (R&C). The oscillator consists of an RC network and an amplifier. The RC network is the timing element, and the amplifier is used to detect the output voltage of the RC network and amplify it. When the DC voltage is applied to the output end of the timing element, due to the charge-discharge relationship of the resistor-capacitor, a triangular waveform will be output, and then it will be amplified and output as a sine wave power supply. This oscillator uses a CMOS buck regulator as its main circuit element, which maintains a stable output frequency and voltage at all times.

In summary, the OH300-50503CF-012.8M oscillator is an integrated RC oscillator with low power consumption and high stability. It has a wide range of applications and its working principle is based on the charge-discharge relationship of the resistor-capacitor.
