摘要: A technique includes locking a locked loop circuit onto a reference clock signal. The locking includes locking the lock loop circuit onto the reference clock signal in response to a first feedback signal provided by a first feedback path and locking the locked loop circuit onto the reference clock signal in response to a second feedback signal that is provided by a second feedback path.

摘要: An embodiment of the present invention is a technique to control clock distribution to a circuit. A scheduler schedules a sequence of a clock distribution of clock signals to a plurality of clock distribution domains (CKDOMs) in the circuit according to a state status of the circuit. A controller controls enabling the clock distribution to the CKDOMs according to the scheduled sequence.

摘要: In some embodiments, a clock generator is provided that provides a generator clock. The clock generator comprises a first clock source to provide a first clock and a second clock source to provide a second clock whose frequency at least indirectly tracks a supply to a clock distribution network. The clock generator selectably provides as the generator clock the first clock when the second clock leads the first clock and the second clock when it lags behind the first clock. Other embodiments are claimed and disclosed herein.

摘要: In general, in one aspect, the disclosure describes a phase-locked loop circuit. The circuit includes an oscillator having a first control input, a second control input, and a third control input, wherein the first control input, the second control input, and the third control input act to control output frequency of the oscillator. The circuit further includes a first charge pump and a second charge pump. A first bias generator is coupled to the first control input of the oscillator and can receive electrical input from the first charge pump. A second bias generator is coupled to the second control input of the oscillator and can receive electrical input from the first charge pump, the second charge pump, and the first bias generator. A third bias generator is coupled to the third control input of the oscillator and can receive electrical input from the second charge pump and the first bias generator.
