TRACKING AND CORRECTION OF TIMING SIGNALS

摘要

Various embodiments include apparatus and methods to track and/or correct timing signals. Timing signals generated from an interface can be compared to the timing signals returned to the interface. A timing delta from the comparison can be applied to calculate a correction value make adjustments that can include adjustment to a subsequent timing signal, adjustment to a reference voltage setting associated with the subsequent timing signal, other adjustments, or combinations thereof. Additional apparatus, systems, and methods are disclosed.

1. An apparatus comprising:
an interface to transmit a timing signal; timing compare circuitry to compare the timing signal to a return timing signal and to provide a timing delta from the comparison; a correction module to calculate a correction value to adjust a subsequent timing signal or to adjust a reference voltage setting associated with the timing signal, the calculation based on voltage shift data derived from the timing delta; and a controller to apply the correction value to the subsequent timing signal or to the reference voltage setting.
