Abstract
A digital clock generation circuit () and method of operation (). A digital clock () produces an output () with a first frequency or a second frequency. A clock control circuit () selectively sets the digital clock () to produce either the first frequency or the second frequency. An excess pulse counter () determines a number of pulses produced by the digital clock () at the second frequency that differs in the number of pulses that would have been produced at the first frequency, had the clock frequency change to the second frequency not occurred. An output phase correction circuit () removes, in response to the digital clock () changing from producing the second frequency to producing the first frequency, the number of pulses from the output () that were counted by the excess pulse counter ().
