A semiconductor device comprises sampling logic, comprising: input sample path selection logic arranged to enable at least one input sample path; sampler logic arranged to receive and sample an input data signal in a serial data stream in accordance with a phase of the at least one enabled input sample path; and transition detection logic arranged to detect transitions within the received input data signal. The input sample path selection logic is further arranged, upon detection of a transition within the received input data signal, to determine if the phase of the at least one input sample path is a phase having a largest window between logic values; and if it is determined that the phase of the at least one input sample path is not the phase having a largest window between logic values, to enable at least one input sample path comprising a more appropriate phase. |
