    摘要: A method of operating a charge pump of a phase-lock assistant circuit includes determining a first relative timing relationship of a phase of a data signal to a phase of a first phase clock. A second relative timing relationship of the phase of the data signal to a phase of a second phase clock is determined, and the first and second phase clocks have a 45° phase difference. An up signal and a down signal are generated in response to the first relative timing relationship and the second relative timing relationship. The charge pump circuit is driven according to the up signal and the down signal.
