Spread-spectrum clocking
A state machine circuit may be used to control a multiplexing circuit that selects and provides respective ones of multiple input clock signals to a clock-synthesizing circuit that generates a synthesized clock signal in response to such input clock signals. The state machine circuit may, for example, be configured so that the synthesized clock signal is a spread-spectrum clock signal and/or a clock signal having a nominal frequency that is greater than a nominal frequency of each of the input clock signals.
