Introduction

Oscillators are designed to generate a continual output signal. These oscillatory signals function in a way that helps subsystems and components of an electronic system to remain synchronized, regardless of any external disturbances.The SIT9120AI-1C1-33E133.333300X oscillator is designed with exceptional precision and stability which make it an ideal choice in a wide range of applications.

Application Field

The SIT9120AI-1C1-33E133.333300X oscillator is a high precision crystal oscillator and is commonly used in high accuracy systems. The oscillator is capable of oscillating frequencies up to 133.333300 MHz, and can provide a reliable timing source for a variety of systems such as telecommunication systems, computer systems, digital data processing systems, and instrumentation systems.In addition, the SIT9120AI-1C1-33E133.333300X oscillator is used in medical applications requiring precise timing, such as medical imaging systems, patient monitoring systems, and laboratory instruments.

Working Principle

The SIT9120AI-1C1-33E133.333300X oscillator utilizes a quartz crystal as its timing element. The quartz crystal consists of two solid pieces of quartz cut in a particular shape, which is placed in an oscillator circuit with an electronic feedback system.When a voltage is applied to the quartz crystal, the crystal vibrates in a consistent frequency. The oscillator circuit amplifies the crystal’s mechanical vibration and an oscillating electrical signal is produced. The frequency of the oscillating signal (the output frequency) is determined by the quartz crystal and is very precise and stable.The output frequency of the SIT9120AI-1C1-33E133.333300X oscillator is ±50 ppm (parts per million) across the -40 °C to +85 °C temperature range. This ensures that the oscillator maintains a stable frequency over a wide temperature range, providing a reliable and precise reference clock signal in severe temperature environments.In addition, the SIT9120AI-1C1-33E133.333300X oscillator features low jitter, low phase noise, and a wide operating voltage range of 3.3V to 5V. This makes the oscillator an ideal choice for digital applications where accuracy and stability is required.

Conclusion

The SIT9120AI-1C1-33E133.333300X oscillator is an ideal choice for high accuracy systems. The quartz crystal-based oscillator provides an accurate and stable reference clock signal over a wide operating temperature range. Its features, such as low jitter, low phase noise, and wide operating voltage, make it suitable for digital applications requiring precise timing.
