Abstract:
Locking time for a phase-locked loop is decreased by selectively controlling a division value of the feedback divider during the first division cycle to reduce the initial phase error. The division value of the feedback divider during the first division cycle is selectively set such that the locking phase relationship between the two phase detector input signals is achieved at the end of the first division cycle.
