Abstract
Real-time clock calibration is accomplished by generating a fast clock signal and a slow clock signal from an uncompensated clock signal; selectively, momentarily, replacing the uncompensated clock signal with the fast and slow clock signal to generate a compensated clock signal; generating from the compensated clock signal a calibration strobe and window trigger; responding to the window trigger to detect any uncompensated clock signal frequency error and responding to the calibration strobe to selectively, momentarily, replace the uncompensated clock signal with the fast or slow clock signal to reduce the clock signal frequency error.
