| titleOfInvention | Jitter detection method and apparatus for phase locked loop |
| abstract | The present invention relates to a jitter detection method and apparatus for a phase locked loop capable of detecting the jitter level of a phase locked loop without using a separate jitter measuring equipment. The jitter detecting device of the present invention provides a phase difference between a reference clock and a feedback clock. A phase locked loop for detecting a signal and generating an oscillating signal of a constant frequency in accordance with the phase difference signal; A variable phase delay unit for switching a plurality of capacitors according to an input delay control signal to delay the phase difference signal from the phase locked loop according to the delay control signal; A comparison unit for comparing the phase difference signal from the phase locked loop with the phase difference signal delayed by the variable phase delay unit to detect a delay period of the phase difference signal; And a lock detector configured to detect that the oscillation signal is located within a lock range after a delay period detected by the comparator.n n n n PLL, Capacitor Delay Stage, Jitter, Lock Range, Lock Delay Control Signal |
