摘要： A digital lock detector for a phase-locked loop. The PLL generates a feedback clock according to a reference clock. The digital lock detector includes a match detector and an arbiter. When a first clock transitions, the match detector checks that whether a second clock transitions in a predetermined time window or not. The match detector generates a match signal if the second clock transitions in the predetermined time window. The arbiter counts a number of the successive match signals and generates a lock signal to indicate a lock state when the number exceeds a first predetermined number.

摘要： A jitter measurement circuit is described comprising delay elements arranged in a serially-connected chain, and first and second sets of circuitry. Each delay elements has an associated delay, an input and an output that produces a delayed version of the signal at the input. The first set of circuitry is configured to detect propagation of the significant instant of the input clock signal through each of the delay elements and produces a pulse in response thereto. The width of the pulse is approximately equal to the delay of the corresponding delay element. The second set of circuitry has one storage element corresponding to each output of the first set of circuitry, for receiving a trigger signal that is timed to correspond to a delay which is approximately half of the total delay of the chain, and for recording in the corresponding storage element any pulse that is active at the time of occurrence of the trigger signal. Thus, a jitter measurement is made based on the pulses recorded in the storage elements after a plurality of trigger signals has occurred.
