It is mostly used in industrial or scientific-oriented fields where high precision and accuracy is required. Additionally, this specific oscillator’s wide frequency range allows for usage in a variety of different scenarios.

Working Principle

The SIT1602BI-81-18S-33.333300T VCO operates on a simple principle. It uses a voltage-controlled oscillator (VCO) that is driven by a phase-locked loop (PLL) system. The VCO is driven by a phase-locked loop (PLL) module that determines the frequency of the output signal according to the frequency of the input voltage. In other words, the input voltage will determine the frequency of the output signal. The PLL module synchronizes the input voltage signal with the VCO frequency by means of a feedback loop. A frequency divider (such as a counter) is used to generate the reference signal which is compared to the input signal. Once the two signals are in sync, the PLL module will give the output signal at the desired frequency. The PLL module controls the input voltage in order to adjust the VCO frequency. This, in turn, controls the output frequency. The PLL module continuously evaluates the frequency of the input signal and output signal in order to make sure the two signals are synchronized.

Conclusion

The SIT1602BI-81-18S-33.333300T oscillator is a type of voltage-controlled oscillator (VCO) operated by a phase-locked loop (PLL) system. It is suitable for a variety of applications due to its wide frequency range and its ability to generate precise frequency signals. Its working principle is based on the input signal being synchronized with the VCO frequency using a feedback loop. The PLL module then adjusts the input voltage in order to control the VCO frequency, thus controlling the output frequency.
