摘要：
A method includes generating a plurality of reference phases of a reference signal and selecting a sub-phase from each of the plurality of reference phases to form a set of selected sub-phases. In the method selecting operates in response to synchronized outputs of a multi-phase phase accumulator that operates synchronously in accordance with one of the sub-phases of the set of sub-phases, and where the outputs of the multi-phase phase accumulator may be synchronized using at least one additional sub-phase.
