Oscillators

Oscillators are circuits or components that generate periodic waves, usually analog waves. They can be used in various applications, such as clocks, timers, security systems, sound systems, and paging systems. In this article, we will discuss the application field and working principle of the 353LB5I447R oscillator.

Application Field

The 353LB5I447R oscillator is a dual quartz crystal oscillator, which has a frequency range of 176.1 MHz to 190.0 MHz. It also features low phase noise, high frequency stability, and low power consumption. Due to its high-performance characteristics, this oscillator is widely used in high-frequency equipment such as mobile phones, base stations, and digital television. It is also commonly used in frequencies such as VHF, UHF, RF, and GPS systems.

Working Principle

The 353LB5I447R oscillator adopts a dual quartz crystal structure. The quartz crystal resonator consists of two quartz plates sharing a piece of metal. The two quartz plates are cut in shape and vibrates when an electric current is applied to the electrodes. They function as a feedback element to support the feedback loop of the oscillator.

The oscillator consists of an input stage, an oscillator stage and an output stage. The input stage drives the oscillator stage, and the oscillator stage drives the output stage. The output stage generates an oscillating waveform that is equal to the frequency of the input signal. The output frequency can be tuned by changing the values of the components of the oscillator.

The 353LB5I447R oscillator uses the required frequency and stability of the quartz crystal to stabilise and control the output waveform. By carefully selecting the components for the oscillator, a stable waveform can be achieved in a wide frequency range. This allows for high-precision operation and ensures that the waveform is both accurate and stable.

In addition, the oscillator also has a temperature compensation feature. This ensures that the oscillation frequency remains within the specified range, even if the temperature of the environment changes. This helps maintain the accuracy and stability of the output waveform.

Conclusion

The 353LB5I447R oscillator is a dual quartz crystal oscillator. It features a wide frequency range, low phase noise, high frequency stability, and low power consumption. It is commonly used in a variety of applications, such as mobile phones, base stations, digital television, VHF, UHF, RF, and GPS systems. The working principle of the oscillator involves an input stage, an oscillator stage, and an output stage, which generate a stable and accurate waveform at the specified frequency. The oscillator also features temperature compensation, which maintains the accuracy of the output waveform even if the environment\'s temperature changes.
