Abstract
A clock generation circuit generates clock signals of a requested frequency and relative phase by dividing a reference clock signal by counting reference clock signal pulses in a counter circuit. The clock generation circuit changes the frequency, and optionally also the phase, of an output clock signal upon request, without generating glitches or missing pulses. The clock generation circuit does not alter the frequency of the output clock signal until a phase pulse associated with the requested phase is asserted, and the counter circuit is in a predetermined state, such as a reset state.
