Abstract
A method includes providing a reference clock signal having a reference period, providing a sampling clock signal having a sampling clock period shorter than the reference period of the reference clock signal, measuring the first subperiod as a first ratio of the first subperiod to the period of the sampling clock signal, measuring the second subperiod as a second ratio of the second subperiod to the period of the sampling clock signal, detecting a starting edge of a clock signal having a clock period greater than the reference period, producing a reconstructed reference signal based on the first ratio, the second ratio, and the detected starting edge, comparing the clock period of the clock signal with a period of the reconstructed reference signal to obtain a differential signal indicating a difference therebetween, and providing the differential signal to user circuitry for calibrating the clock signal.
