Working Principles

The SI5335B-B08248-GMR is a clock generator and multiplier IC that generates multiple clock outputs from a single input source. It uses a combination of PLL (Phase-Locked Loop) and VCO (Voltage-Controlled Oscillator) techniques to generate precise and stable clock signals. The input clock can be provided through a crystal or an external reference clock. The IC then multiplies the input frequency and distributes it to the desired output pins, which can be configured for various output formats.
