It is used to generate a consistent, stable frequency for use in a variety of applications. Oscillators are available in a wide range of frequencies, from low frequencies to ultra-high frequencies, and in a variety of sizes and shapes.

Application Field

SIT8208AI-81-18E-28.636300X oscillator is widely used in AC/DC motor drivers, motion controllers, stepping motors, frequency converters, gate drivers, power supplies, smart phone signal transmission, digital home appliances, video game control, consumer electronics, digital cameras/camcorders, medical/analytical instruments and communication systems such as cellular base station, Wi-Fi/Bluetooth and GPS.

Working Principle

The basic operation of a SIT8208AI-81-18E-28.636300X oscillator can be broken down into three steps. First, a voltage is applied to its input, typically a sine wave. This voltage causes the capacitor to charge, storing energy in it. Once the capacitor is fully charged, it releases this stored energy back through the circuit, driving the oscillator in the opposite direction. This positive and negative charge cycle produces the oscillating wave form, otherwise known as the output signal. The oscillator’s output signal is then further modified by an external circuit using components such as resistors, capacitors and inductors to achieve the desired output signal frequency and waveform. Some applications may need to allow for variable frequencies, in which case the speed of the output signal will be adjusted by controlling the resistor or capacitor values.

Conclusion

In conclusion, SIT8208AI-81-18E-28.636300X oscillator is a common type of oscillator typically used in AC/DC motor drivers, motion controllers, frequency converters, and power supplies. Its working principle is based on a capacitor storing energy and releasing it back through the circuit, driving the oscillator in the opposite direction and producing a consistent, stable output frequency. The output signal can be further modified using external components such as resistors, capacitors and inductors to achieve the desired signal frequency and waveform.
