Oscillators are devices that generate periodic or aperiodic signals over a range of frequencies, and SIT8208AI-32-28E-3.570000X is an example of such device. In this article, we will give an overview of its application field and explain its working principle.

Application Field

The SIT8208AI-32-28E-3.570000X oscillator is mainly used in dust-proof, moisture-proof, and vibration-proof industrial monitoring, data acquisition, instrumentation, machine vision, and measurement applications. This device also has an excellent temperature compensation function and frequency stability in conditions of extreme temperatures. With an indigenous MEMS crystal oscillator process and an acceleration-sensing capacitive structure, it offes a comprehensive, integrated, best-in-class oscillator solution that is resistant to shock and vibration.

The device also has the ability to operate in harsh electromagnetic environment. It has strong anti-jamming capability while its surface creep during operation is one-fifth of traditional SAW-resonator oscillators. SIT8208AI-32-28E-3.570000X also features integrated frequency pulling prevention, which is widely used in vibration-proof applications.

Working Principle

The SIT8208AI-32-28E-3.570000X oscillator uses MEMS technology to achieve higher levels of frequency stability and phase noise. The MEMS module consists of a micro-electrical mechanical system in which an oscillator chip has an oscillator frequency resonator and an accelerometer capacitor. The resonator vibrates at a specific resonant frequency which is determined by its physical dimensions. The accelerometer capacitor is connected to it and integrated into the chip. The accelerometer capacitor detects the movement of the resonator and produces an additional electrical signal that is combined with the resonator’s signal to stabilize signals and prevent frequency drift.

The MEMS module also contains a driver circuit which controls the speed and power of the oscillator. This circuit is connected to a CMOS clock circuit. This clock circuit amplifies the frequency signal from the MEMS and provides power to it. The clock signal is then delivered to the output pins. Finally, the output pins deliver the signal to the device that requires an oscillator signal, such as a radio receiver.

The SIT8208AI-32-28E-3.570000X oscillator is an important component for many industrial, automotive, and consumer applications. It offers improved frequency stability, phase noise, and shock and vibration resistance over traditional solutions while providing an improved level of power consumption. Its unique design coupled with a powerful CMOS clock circuit makes the SIT8208AI-32-28E-3.570000X oscillator the ideal choice for many applications.
