Abstract
A clock selection circuit for selecting one of a plurality of clocks as an output clock. When the selection circuit switches between two of the plurality of clocks for output, the currently output clock is removed from the output. The removal of the currently output clock is performed synchronously to the currently selected clock. The newly selected clock is then coupled to the output. Coupling of the newly selected clock is performed synchronously to the newly selected clock.
