The working principle of a SI5351A-B04963-GTR is based on the phase-locked loop (PLL) architecture. The phase locked loop consists of two main components, the input clock and the phase locked loop circuit. An input clock is generated by the crystal oscillator and this clock is supplied to the phase locked loop circuit. The phase locked loop circuit, in turn, compares the input clock to the initial reference frequency and adjusts its output frequency so that the difference between the two signals is minimized. The result is a stable and accurate output frequency, regardless of changes in the initial reference frequency.

Overall, the SI5351A-B04963-GTR is a cost-effective solution for providing clock generation, PLL and frequency synthesis for a range of applications. It is easy to configure with a variety of digital systems and provides accurate, stable, and synchronous frequencies. Furthermore, the ability to output multiple frequencies from the same module makes it an ideal solution for SSB and FM radio applications.
