Working Principles

The SI5355A-B05422-GMR utilizes a fractional-N PLL (Phase-Locked Loop) architecture to generate accurate clock signals. It takes an external reference clock or crystal oscillator input and uses a programmable divider to generate the desired output frequencies. The integrated jitter attenuator helps reduce unwanted noise and distortion in the generated clock signals, resulting in improved signal quality.

The device is controlled through an I2C interface, allowing users to program the output frequencies, configure the PLL settings, and adjust other parameters as needed. The flexible clock distribution feature enables the generated clocks to be distributed to multiple devices within a system.
