In terms of its working principles, the SI5335C-B06483-GMR follows the principles of PLL synthesizers. It uses a VCO as a reference oscillator and uses its own inputs to generate a precise output frequency. The device uses a reference frequency input that can be a crystal oscillator or a reference frequency from a digital source. It also has a feedback circuit, consisting of a divider and a phase detector, to correct for any errors in the generated output frequency.

This feedback circuit allows the device to constantly monitor and adjust the output frequency until it matches the reference frequency. The device also has a loop filter, which helps to reduce the amount of jitter on the output frequency. The loop filter also prevents the output frequency from rapidly changing, as this can create unwanted harmonics in the generated signal.
