Abstract:
1. An electronic device, comprises: a number of sub-systems coupled via an interface, wherein 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; 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 either sent to or generated by the interface to sample the received input data in a middle region of a data bit period in response to the cross correlation and disable at least one data path comprising at least one unselected phase from the plurality of phases, wherein in response to determining there is no phase of a respective data path that matches a cross-correlation threshold in a first sampling time period, the logic for performing cross correlation performs cross correlation over a subsequent sampling time period.
