Abstract
A serial bus clock frequency calibration system and a method thereof are disclosed herein. The system utilizes a first frequency calibration device and a second frequency calibration device both to share an oscillator as so to perform two-stage clock frequency resolution calibrations for generating different frequency-tuning ranges. This can bring an optimal frequency resolution and greatly reduce system complexity and save element cost.
