Crystals

Crystals are essential components for many electronic devices. From providing timing reference for applications such as cellular phones and compass navigation, to providing phases for amplifiers and oscillators for television circuits, crystals are ubiquitous. Among their various features, an important one is the ability to store and release energy. One type of crystal that is particularly suited for energy storage and release is the IAT402F27022.

IAT402F27022 Application Field

The IAT402F27022 is primarily used as a voltage-controlled oscillator (VCO) in aerospace and military applications. It is primarily used for pitch or frequency control and provides a predictable frequency-scaling characteristic when a voltage-control input is provided. This makes it well-suited for applications where the frequency of a signal needs to be accurately controlled over a wide range.

IAT402F27022 Working Principle

The IAT402F27022 works by using a combination of two quartz crystals; an oven-controlled crystal oscillator (OCXO) to provide frequency accuracy, and a voltage-controlled crystal oscillator (VCXO) to provide frequency control. The OCXO provides a stable, highly accurate reference frequency, which is then compared to a reference frequency provided by the VCXO. When the two frequencies match the oscillator is in lock, and when there is a mismatch the reference frequency is adjusted until the oscillator is in lock again. The voltage-controlled input is used to adjust the frequency of the VCXO, and thus the frequency of the output signal. By this method the IAT402F27022 is able to provide an output frequency that is both accurate and tunable.

Conclusion

The IAT402F27022 crystal is a versatile oscillator that can be used in a wide range of applications. It is highly accurate and provides a predictable frequency-scaling characteristic when voltage-control input is provided. With its wide range of features and reliability, the IAT402F27022 is essential for a variety of applications where a stable and tunable frequency is needed.
