  • Patent number: 7786816
    Abstract: An oscillating signal in an oscillator is caused to phase shift toward the phase of an input signal coupled to the oscillating signal. The resonant frequency of the oscillator is about equal to an integer multiple of the frequency of the input signal. The input signal may be generated in a pulse generator to have an input pulse duration less than or equal to that of the oscillating signal. The oscillator circuit may be used as a filter to filter pulse width variations or to filter jitter from a reference clock. The oscillator circuit may also serve as a buffer by amplifying the input signal. Phase interpolation can be obtained by coupling at least one input signal with at least one oscillating signal.

  • Patent number: 7688925
    Abstract: An IO method and system for bit-deskewing are described. Embodiment includes a computer system with multiple components that transfer data among them. In one embodiment, a system component receives a forward strobe signal and multiple data bit signals from a transmitting component. The receiving component includes a forward strobe clock recovery circuit configurable to align a forward strobe sampling clock so as to improve sampling accuracy. The receiving component further includes at least one data bit clock recovery circuit configurable to align a data bit sampling clock so as to improve sampling accuracy, and to receive a signal from the forward strobe clock recovery circuit that causes the data bit sampling clock to track the forward strobe sampling clock during system operation.
