Oscillators

Oscillator circuits are the foundation for a variety of electronics applications, including the generation of an accurate time base for a digital system or the generation of a carrier signal for communication systems. The 353VB3A184R is one of many oscillator circuits that can offer precision over a wide range of frequencies.

Application Field

The 353VB3A184R is designed to provide accurate, wide-range frequency control and stable time base generation in radar, communication, imaging, metrology, and other electronic control systems. This crystal oscillator design is capable of operation in both Air and vacuum environments, and offers stability and reliability to support a number of mission-critical applications.

Working Principle

Crystal oscillators utilize a quartz crystal resonator as the frequency-determining component. By applying a driving voltage to the quartz crystal resonator, it will respond with an oscillating frequency that is determined by its natural resonant frequency. From this oscillating frequency, a signal can be extracted to provide a stable time base or generate a carrier. Due to their accuracy, quartz crystals are used in a wide range of timing applications.

In the 353VB3A184R design, a quartz crystal resonator acts as a double-tuned circuit, with the crystal formed in a thin film deposited on the surface of a printed circuit board. The crystal resonator is driven by an external voltage source, which induces an oscillating electrical signal. This signal is routed through a filter which attenuates higher frequency harmonics, additional amplifier stages, and finally a frequency doubler stage before being outputted as a stable oscillating frequency with low jitter. This oscillating frequency can then be used as needed for its application.

Conclusion

The 353VB3A184R provides effective frequency control in both air and vacuum environments, making it an ideal choice for radar, communication, imaging, metrology, and other mission critical applications. By applying a driving voltage to the quartz crystal resonator, a stable oscillating frequency at a specified frequency can be obtained. The use of a filter and Amplifier stages ensures that the oscillating frequency is stable and of low jitter.
