An oscillation tuning circuit is provided and includes a first circuit. The first circuit receives an input data stream with a known time interval, producing a first output signal having a first period, determines a first error signal representing a difference between the known time interval and a measured duration of the known time interval, determines a reference error signal according to a predetermined multiple of the first period, and adjusts the first period according to the first error signal and the reference error signal, wherein the known time interval is associated with a period between a first occurrence of and a second occurrence of a predetermined bit pattern in the input data stream.
