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