1. An apparatus for tuning a frequency synthesizer device toward a prescribed frequency, the apparatus comprising:
memory for storing a plurality of prescribed coarse curves in a sequential frequency order;
a selector configured to select a first coarse curve of the set of prescribed coarse curves for producing first output signals having a first output frequency at an output of the frequency synthesizer; and
a comparator configured to compare the prescribed frequency and the first output frequency to produce a magnitude value,
the selector further configured to select a second coarse curve of the set of coarse curves as a function of the magnitude value for producing second output signals having a second output frequency at the output of the frequency synthesizer closer than the first output frequency to the prescribed frequency, the selector configured to select the second coarse curve out of the sequential frequency order as a function of the magnitude value.
