Abstract
In a clock switching apparatus, a corresponding mask clock signal is generated for at least one of first and second clock signals. A mask clock signal has an interval of a predetermined logical level near the switching between the clock signals. Each mask clock signal is synchronized to the first and/or second clock signals. Such an interval in the mask clock signal prevents occurrence of glitches in an output clock signal that is switched between at least one mask clock signal and/or at least one clock signal.
