Working Principle

The SIT8209AC-83-33E-133.333000Y oscillator operates on the principle of phase-locked loop (PLL) technology. The device is able to generate stable signals over a wide frequency range with low phase noise. This is achieved by locking the output frequency to an external reference frequency using a feedback loop. The reference frequency is used to guide the output frequency to a specified frequency or frequency range.

The oscillator is comprised of a voltage-controlled oscillator (VCO), a phase-frequency detector (PFD), a charge pump, and an external frequency reference. The PFD compares the output frequency of the oscillator to the reference frequency and generates a voltage-level difference. This difference is used to drive the charge pump, which adjusts the VCO frequency and allows the oscillator to lock to the reference frequency.

The SIT8209AC-83-33E-133.333000Y oscillator is constructed in a 4 x 4 mm package and is temperature compensated. The device features an output enable/disable pin and an accurate VCO adjustment range of +/-30 ppm.
