Abstract
In general, in one aspect, the disclosure describes an apparatus for calibrating signals. The apparatus includes a receiver pair to receive a differential signal and a reference signal and to generate at least one comparison signal reflecting where a first signal of the differential signal and a second signal of the differential signal cross each other with respect to the reference signal. The second signal is a negative compliment of the first signal. The apparatus further includes a phase detector to determine a phase error based on the at least one comparison signal. The apparatus also includes an edge delay control driver pair to adjust the differential signal based on the phase error.
