Abstract
One embodiment of a method of generating a clock signal and synchronizing the generated clock signal with a digital data stream comprises generating a clock signal using an oscillator, identifying a transition in a portion of the data stream, and synchronizing a transition of the clock signal with the identified transition in the data stream by changing a state of the oscillator using control circuitry in response to the identification of the transition in the data stream, wherein the clock signal is synchronized with the data stream for both situations where the oscillator operates at a frequency greater than the data rate and where the oscillator operates a frequency less than the data rate. Other methods and systems are also provided.
