摘要： Devices, systems, and methods for spread spectrum clock generation are disclosed. The devices, systems, and methods generate a clock signal at a frequency and generate a voltage output based on the frequency of the clock signal, wherein the generated voltage output is indicative of the frequency of the generated clock signal. The devices, systems, and methods also compare the frequency of the clock signal generated to a desired frequency output by comparing the generated voltage output to a voltage reference and adjust the frequency of the clock signal generated based on the results of the comparison.

摘要： In one example, a method includes outputting, during a first phase, a first current level at a connector, and outputting, during a second phase, a second current level at the connector, wherein the second current level is complementary to the first current level. In this example, the method also includes determining whether or not a voltage level of the connector satisfies a threshold, and responsive to determining that the voltage level of the connector satisfies the threshold, determining that the connector is floating.

摘要： In one implementation an output signal of an oscillator is varied to be within a desired frequency band with respect to a reference signal, the output signal having a plurality of phases. The implementation may include comparing the output signal with the reference signal, counting falling edges about each phase of the number of phases in a predetermined time period and summing to define a count output; comparing the count output with a product of the number of phases of the output signal and the factor to define a comparison, generating a control signal based upon the comparison, and inputting the control signal to the oscillator to alter the output signal thereof.
