Abstract
Embodiments of the present invention disclose a method and device for selecting a sampling clock signal. The method includes: obtaining, by a logic chip, a data edge of a data signal and a clock edge of a clock signal, selecting a sampling edge according to the data edge and the clock edge, and sending a selecting signal corresponding to the sampling edge to a selector; and selecting, by the selector, a sampling clock signal according to the selecting signal. The technical solutions provided by the embodiments of the present invention can solve problems of poor system maintainability and high cost of operation and maintenance because a receiver device needs to select a sampling clock signal through manual configuration in the synchronous serial-port communication in the prior art.
