ABSTRACT:
Clocking circuitry includes a first clock generator to generate a first clock signal and having a first duty cycle correction input, and a second clock generator to generate a second clock signal and having a second duty cycle correction input. Some embodiments have more than two clock generators. A multiplexer selects between the clock signals from the clock generators. The multiplexer has a first input coupled to the first clock signal and has a second input coupled to the second clock signal, and has a clock output coupled to a clock input of a duty cycle circuit. The duty cycle circuit receives the selected clock signal from the multiplexer and generates a duty cycle correction signal.
