Working Principles

The SI5350C-B06847-GTR utilizes a fractional-N PLL (Phase-Locked Loop) architecture to generate precise clock signals. It takes an external crystal oscillator as the reference input and uses a programmable feedback divider to synthesize the desired output frequencies. The PLL's phase detector compares the divided output signal with the reference signal, continuously adjusting the feedback divider to maintain the desired phase relationship.
