FIELD: radio engineering, communication.SUBSTANCE: proposed method comprises supplying to initial setting inputs of all ADCs with oversampling (ADCO) of initial setting pulses, then supplying periodic clock signals to clock inputs of all ADCO. There goes generation of data availability signal by ADCO, where each ADC with a chase lock node. Data availability pulses from each ADC are sent to the first input of chase lock node, connected to the ADC. The other input of all chase lock nodes is supplied with periodic sync control pulses, generated by reference clock. The latter pulses are compared to data availability pulses against timestamps of arrival in each chase lock node. If the predefined offset limit is exceeded, the initial setting pulse is generated in corresponding chase lock node. The pulse is sent to initial setting input of the connected ADC via OR scheme.EFFECT: automation of sync recovery process for ADCs with oversampling.2 dwg |
