What Are Oscillators and How Do They Work?

Oscillators are the backbone of many components in a wide range of electronic equipment. They are an important component in everything from radio receivers to timer circuits, playback systems, digital signal processing (DSP) systems, and more. In this article, we will take a look at what exactly oscillators are and how they work.

What Is an Oscillator?

An oscillator is an electronic circuit that produces a consistent periodic waveform output with limited noise. It is used in many electronic systems for several different purposes and types of applications. Oscillators come in different shapes and sizes, as well as in several different forms, such as analog, digital, and mixed signal.

SIT9120AI-1DF-33E156.25000X Oscillator Applications

The SIT9120AI-1DF-33E156.250000X is a 0.25 MHz resonator-based oscillator. It is designed for personal computers, peripherals, medical, and communication devices that require stable and reliable frequency control. The oscillator provides a wide operating temperature range (from -40 to +85 degrees Celsius). It also comes with a wide selection of frequency options, and it requires low input voltage (1.8v to 3.3v).

The Working Principle of SIT9120AI-1DF-33E156.25000X Oscillator

The SIT9120AI-1DF-33E156.25000X Oscillator works on an oscillator circuit based on quartz crystal resonator and an inverting amplifier. In this type of Oscillator, the quartz crystal provides the desired frequency of oscillation and the inverting amplifier provides the necessary gain to make the circuit oscillate. The Oscillator circuit is made up of the quartz crystal, which acts as a resonator and the inverting amplifier. The quartz crystal has two electrodes, an anode and a cathode, which act as the conductors for the AC current signal. The AC signal frequency is determined by the resonance characteristics of the crystal. This frequency is picked up by the amplifier and amplified in an inverting manner (which means the polarity of the output signal is opposite to that of the input signal).The output of the inverting amplifier is then passed through an LC filter, which is typically an inductor and capacitor in series, which was used to reduce unwanted noise and harmonics from the signal. This filtered output is then passed through a frequency transformer, such as a Schmitt trigger, which is used to further reduce noise and ensure a clean signal.

Conclusion

The SIT9120AI-1DF-33E156.25000X Oscillator is a 0.25 MHz resonator-based oscillator that is designed for personal computers, peripherals, medical, and communication devices that require stable and reliable frequency control. The oscillator works on an oscillator circuit based on quartz crystal resonator and an inverting amplifier, and is equipped with a wide selection of frequency options and requires low input voltage. As such, oscillators such as the SIT9120AI-1DF-33E156.25000X are a vital component in many electronic devices and systems.
