Abstract
A phase rotation control method includes: detecting whether a phase of an output clock signal of a phase interpolator is going to be switched from a current quadrant to a next quadrant according to a trigger signal to generate a state signal; determining a phase adjustment direction of the output clock signal according to an original phase control signal and the state signal to generate a update signal and first control signals; generating the trigger signal and a selection signal according to the update signal and generating second control signals according to the state signal and the first control signals; and when the phase of the output clock signal is switched to the next quadrant, outputting the second control signal as a phase control signal according to the selection signal, in which the phase interpolator adjusts the phase of the output clock signal according to the phase control signal.
