Abstract
A glitch-free clock switching circuit with clock loss tolerance and an operation method thereof and a corresponding glitch-free clock switching device are provided. The glitch-free clock switching circuit includes a first and a second stuck-status detection circuits, a first and a second reset synchronizers and a glitch-free switching core circuit. The glitch-free switching core circuit performs clock switching according to a clock switching signal to switch an output clock of the glitch-free clock switching circuit from an original clock source to a target clock source, where the original clock source and the target clock source represent one and the other of a first clock source and a second clock source, respectively; wherein the glitch-free clock switching circuit performs the clock switching based on a first synchronized reset signal and a second synchronized reset signal to provide the clock loss tolerance.
