Abstract
An automatic clock calibration circuit includes a source of clock signals and an equal number of corresponding clock reference signals. Corresponding delay elements are connected between the source and the load driven by each of the clock signals. A phase frequency detector detects the phase differences between each clock signal, at the point at which it is applied to its load, and its corresponding clock reference signal. A microcontroller adjusts the delay of the delay elements according to the detected phase differences.
