Electronic device, integrated circuit and method for selecting of an optimal sampling clock phase

摘要

An electronic device comprises a number of sub-systems coupled via an interface. One of the number of sub-systems comprises logic for receiving a frame of input data having a plurality of phases on respective data paths. The electronic device further comprises logic for performing cross correlation on the received input data with a pre-determined bit pattern, operably coupled to selection logic, for selecting a single phase from the plurality of phases sent to the interface to sample the received input data in a middle region of a data bit period in response to the cross correlation.
