Abstract
A system clock switching apparatus, which includes a clock source for providing a reference clock signal; a frequency divider electrically connected to the clock source for dividing the reference clock signal to produce a frequency-divided signal and a system clock signal; and an enable signal generator electrically connected to the frequency divider for dividing the frequency-divided signal to produce at least one enable signal. The frequency divider switches the frequency of the system clock signal at a time period corresponding to a pulse edge of the frequency-divided signal.
