Working Principles

The SI5335C-B05010-GMR is a clock generator IC that uses a phase-locked loop (PLL) to synthesize and distribute precise clock signals. It takes an input clock signal and generates multiple output clocks with programmable frequencies, phases, and formats. The PLL locks onto the input clock and generates a high-frequency reference signal, which is then divided and multiplied to produce the desired output frequencies. The output clocks can be further adjusted using the integrated I2C interface.
