Abstract
A phase locked loop employed in a synthesizer includes a coarse tuning means to enable the VCO in the loop to be tuned within the acquisition range of the loop to thus enable the loop to fine tune the VCO to the desired output frequency. The coarse tuning means is removed from the loop when the VCO frequency is within the acquisition range.
