Abstract
A circuit includes first and second frequency divider circuits and first storage circuits. Each of the first and the second frequency divider circuits receives periodic input signals and generates a periodic output signal having a frequency of one of the periodic input signals in a bypass mode. The periodic output signal of each of the first and the second frequency divider circuits has a fraction of a frequency of one of the periodic input signals in a frequency divider mode. Each of the first storage circuits stores an enable signal in response to the periodic output signal of one of the first frequency divider circuits. The enable signals stored in the first storage circuits enable the second frequency divider circuits in the frequency divider mode. The circuit may include second storage circuits storing enable signals that enable a subset of the first frequency divider circuits in the frequency divider mode.
