ABSTRACT:
A method for autocalibrating a plurality of phase-delayed clock signal edges within a reference clock period includes measuring delay spacing between the plurality of clock signal edges, calculating programmed delay spacing, calculating ideal signal edges from the programmed delay spacing and adjusting the clock signal edges to match the respective ideal signal edges. A plurality of calibrated clock signal edges is produced that are selectively available to a user.
