Abstract
A multi-phase clock switching device includes a plurality of phase selection circuits. The phase selection circuit is used to receive a plurality of phase clock signals and determine how to output the phase clock signals to generate an output signal according to a switching signal. The phase selection circuit includes a selection unit and a protection unit. The selection unit receives at least a phase clock signal and determines how to output a phase clock signal according to the at least a phase clock signal and a selection signal. The protection unit determines how to generate the selection signal according to the phase clock signal and the switching signal.
