Abstract:
1. An apparatus, comprising: a local dock signal; a sampling unit to sample an input line at three points in time, the sampling operations to determine a value for the input line at a first point in time, a value for the input line at a second point in time after the first point in time, and a value for the input line at a third point in time after the second point in time; and a voter block to cause the local clock signal phase to be adjusted if the values for the first and third points in time are equal and if the value for the second point in time is not equal to the values for the first and third points in time, and the voter block to cause the local clock signal phase to be advanced if the values for the first and third points in time are not equal and if the value for the second point in time is equal to the value for the third point in time.
