Abstract: A Phase-locked Loop (PLL) (204) that is dynamically and automatically altered in response to changes in the jitter of the input is disclosed. The Analysis Block (304) receives one or more inputs from the PLL operation. The output of the Analysis Block (304) triggers a change in the Parametric Control Block (308) which in turn imparts changes on the gains of one or more of the various components or the value of &ohgr;N of the PLL Low Pass Filter (116). The dynamic change to at least one parameter of the PLL adjusts the tradeoff between removing as much of the jitter as possible and having a responsive system that has a reduced risk of buffer underflow or overflow. This abstract is provided as a tool for those searching for relevant disclosures, and not as a limitation on the scope of the claims.
