Title:
COMMUNICATION APPARATUS AND SIGNAL SAMPLING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/045142
Kind Code:
A1
Abstract:
A communication apparatus and a signal sampling method. The communication apparatus comprises: a clock control circuit, a data sampling circuit and a clock recovery circuit, wherein the clock control circuit is used for determining a sampling clock offset of the data sampling circuit, and generating a first clock control signal according to the sampling clock offset, the first clock control signal being used for adjusting a sampling clock of the data sampling circuit; the clock recovery circuit is used for adjusting the sampling clock of the data sampling circuit according to the first clock control signal, and sending a clock signal to the data sampling circuit; and the data sampling circuit is used for sampling an input analog signal according to the clock signal. By means of the communication apparatus, a sampling clock of a data sampling circuit can be locked at an optimal sampling moment, and therefore useful information of an original analog signal can be retained in a digital signal after sampling without oversampling the original analog signal. Moreover, the complexity of the data sampling circuit is not increased even in a large-bandwidth scenario.
