  • PHASE- OR FREQUENCY-LOCKED LOOP CIRCUIT HAVING A GLITCH DETECTOR FOR DETECTING TRIGGERING-EDGE-TYPE GLITCHES IN A NOISY SIGNAL
    Publication number: 20070120584
    Abstract: A phase- or frequency-locked loop circuit (200) that generates an accurate output signal (ACC_SYN_OUT) even in the presence of edge-triggering-type glitches (148, 304A, 304B) in the input reference clock signal (REF_CLK). The locked-loop circuit includes a phase or frequency difference detector (216) and a glitch detector (208) that generates a trigger signal (GLITCH_DETECTED) upon detection of at least one glitch. The trigger signal resets the difference detector so as to abort the updating of the output signal that the glitch would otherwise cause.
