摘要： Embodiments of a clock circuit are described. This clock circuit includes an oscillator, which includes a resonance circuit having a resonance frequency, that outputs a first clock signal having a first frequency. Furthermore, a digital controller is coupled to the oscillator. This digital controller modifies the resonance frequency of the oscillator during a first mode of operation of the clock circuit, and the modifying is ceased during a second mode of operation of the clock circuit. In addition, on injection circuit is coupled to the oscillator. This injection circuit provides a second clock signal having a second frequency to the oscillator. Note that the second clock signal injection locks a phase and/or the first frequency of the first clock signal. Also note that a ratio of the first frequency to the second frequency is greater than or equal to one.

摘要： A data receiver circuit (206) includes first and second interfaces (221) coupled to first and second respective transmission lines (204). The first and second respective transmission lines comprise a pair of transmission lines external to the data receiver circuit. The first and second interfaces receive a transmission signal from the pair of transmission lines. A common mode extraction circuit (228) is coupled to the first and second interfaces to extract a common-mode clock signal from the received transmission signal. A differential mode circuit (238) is coupled to the first and second interfaces to extract a differential-mode data signal from the received transmission signal. The extracted data signal has a symbol rate corresponding to a frequency of the extracted clock signal (e.g., —the symbol rate may be twice the frequency of the extracted clock signal). The differential mode circuit is synchronized to the extracted clock signal.

摘要： A data transmission circuit includes a clock driver to obtain a clock signal having a first rate and to drive the clock signal onto one or more transmission lines. The data transmission circuit also includes a timing circuit to obtain the clock signal and to generate a symbol clock having a second rate. The first rate is a multiple of the second rate, wherein the multiple is greater than one. The data transmission circuit further includes a data driver synchronized to the symbol clock. The data driver obtains a data signal and drives the data signal onto the one or more transmission lines at the second rate. The data signal and the clock signal are driven onto the one or more transmission lines simultaneously.

摘要： A circuit to test phase linearity of a phase synthesizer, which synthesizes an output clock having a phase corresponding to a digital phase value input to the phase synthesizer. A digital counter provides the digital phase value to the phase synthesizer. The digital counter receives a counter clock synchronized with an input clock. The digital phase value is stepped by the digital counter, thereby shifting the frequency of the output clock. The output clock is analyzed with respect to phase linearity of the phase synthesizer to produce a phase linearity analysis output.
