HOMOLOGOUS OUT-OF-PHASE CLOCK GENERATION APPARATUS AND METHOD, AND DEVICE

WIPO Patent Application WO/2023/092964

A1

Provided in the present invention are a homologous out-of-phase clock generation apparatus and method, and a device. The apparatus comprises: an automatic calibration module, a delay configuration module and a delay module, which are connected in sequence, wherein the automatic calibration module is used for acquiring, according to an input automatic calibration enable signal, first information of a delay unit which is correspondingly started by a target phase difference, and determining, according to the first information, second information of a delay unit corresponding to an input first phase difference; the delay configuration module is used for outputting a first control signal according to the second information; and the delay module is used for starting a delay unit in the delay module according to the first control signal and a source clock, and outputting a homologous out-of-phase clock. By means of the present invention, a homologous out-of-phase clock with an accurate phase difference can be efficiently generated.
