Abstract
A divider apparatus for use within a phase-locked loop having an output terminal at which an output frequency is produced. The apparatus includes a prescalar circuit configured to produce a prescaled signal by dividing the output frequency in response to a mode select signal. A first programmable counter is disposed to receive the prescaled signal and to produce the mode select signal. In addition, a second programmable counter is disposed to receive the prescaled signal and to produce a divided signal utilized by the phase-locked loop. The apparatus further includes a control circuit connected to the first programmable counter and to the second programmable counter, the control circuit providing a first resynchronization signal to the first programmable counter and a second resynchronization signal to the second programmable counter.
