Abstract:
1. A method of adjusting an output signal generated by an oscillator, the method comprising: detecting a timing difference between an incoming signal and the output signal generated by the oscillator; generating a first signal using a first randomizing digital signal attenuator, wherein the first signal is based, at least in part, on the timing difference, and wherein said generating a first signal includes providing an indication of the sign of the timing difference to the first randomizing digital attenuator; generating a second signal using a second randomizing digital attenuator, wherein the second signal is based, at least in part, on the timing difference, and wherein said generating a second signal includes providing an indication of the sign of the timing difference to the second randomizing digital attenuator; integrating the second signal to generate an integrated signal; and generating control signals for the oscillator based, at least in part, on the first signal and the integrated signal.
