Abstract
A method and system in a data processing system for resynchronizing a received data stream with a master clock having a master clock frequency, wherein the received data stream is clocked with a received data clock that is out of phase with the master clock by an arbitrary number of degrees. The master clock and the received data clock are compared at a frequency of a resynchronization clock for a predetermined number of times to produce comparison results. The resynchronization clock frequency may be less than the frequency of the master clock. The comparison results are analyzed to produce a relative phase indicator. In response to the relative phase indicator exceeding, or being less than, a phase shift threshold, the received data stream is reclocked at a rising or falling edge of the master clock to produce a resynchronized data stream, wherein the resynchronized data stream is synchronized with the master clock and contains the data of the received data stream.
