Oscillators

Oscillators are electronic circuits that are used to generate periodic or continual signals for various uses such as timers, filters, communications, etc. This article will focus on one specific oscillator, the SIT8208AI-3F-18S-62.500000T, and its application field and working principle.

Application Field

The SIT8208AI-3F-18S-62.500000T oscillator is a voltage-controlled quartz crystal oscillator (VCXO) which is widely used in applications such as frequency synthesisers, frequency hopping systems, phase-locked loops, and high-precision clocks. It can be used in both digital and analogue systems and typically can operate between -10 and +60 degrees C.

Working Principle

The SIT8208AI-3F-18S-62.500000T VCXO works on a principle called the Piezo-electric effect. This effect describes how a physical deformation on a crystal can generate a small electrical voltage or current when an external force is applied. This external force can be supplied to the crystal in the form of an electrical signal, which causes a physical reaction inside the crystal, changing its shape and thus generating the voltage or current.

This voltage or current is used as input to the oscillator circuit, which amplifies the signal and feeds it back into the crystal, creating a continuous cycle and allowing the quartz crystal oscillator to produce a stable, consistent frequency output, even if the voltage input varies. Among many other benefits, the ability to adjust the frequency by controlling the applied voltage makes these oscillators widely used in precision timing applications.

Conclusion

The SIT8208AI-3F-18S-62.500000T VCXO oscillator is a reliable and precise device capable of producing consistent signals even in changing voltage conditions. It is widely used in frequency synthesis, frequency hopping, phase-locked loop, and high-precision clock applications and typically has an operating temperature range of -10 to +60 degrees C. This oscillator works on the principle of the Piezo-electric effect, which causes the crystal shape to change when a voltage is applied, producing a voltage or current which is used to create a feedback loop and generate a stable output signal.
