Working Principle of SIT8208AI-8F-28E-33.333000Y

The SIT8208AI-8F-28E-33.333000Y oscillator utilizes phase-locked loop technology, which is based on a feedback principle. The oscillator consists of a VCO, a phase comparator and a low-pass filter. This configuration forms a negative feedback loop, allowing the circuit to produce a stable output frequency.

The VCO is an electronic circuit that generates an oscillation. Depending on the input signal, the VCO can generate a wide range of frequencies. This oscillation output by the VCO is then fed to the phase comparator. In the phase comparator, the output from the VCO is then compared with the reference clock signal.

The low-pass filter is used to smooth out the output of the phase comparator. The output of the filter can be in either analog or digital format, depending on the requirements of the specific application. The output from the filter is then fed back to the VCO, forming a negative feedback loop. This loop results in a stable oscillation, thus providing a stable output frequency for the oscillator.
