PHASE-LOCKED LOOP(PLL) HAVING EXTENDED TRACKING RANGE |
摘要 |
A method for extending a tracking range of a PLL includes the steps of: establishing an initial tracking window of the PLL, the tracking window having a first width associated therewith; and dynamically adjusting the tracking window of the PLL within an extended tracking range when a frequency of an input signal supplied to the PLL is outside of the tracking window, the extended tracking range having a second width associated therewith which is greater than the first width.
