Abstract:
An apparatus for dynamically adjusting a final output frequency, the apparatus comprising:a phase detector that receives a reference frequency is a first input frequency and is, wherein the reference frequency is compared with a second input frequency to generate a first output frequency; a variable frequency oscillator that generates a second output frequency responsive to the first output frequency from the phase detector; a First frequency divider that receives the second output frequency from the variable frequency oscillator, wherein the first frequency divider divides the second output frequency by a fixed first value to generate the second input frequency to the phase detector; and a second frequency divider that receives the second output frequency from the variable frequency oscillator, wherein the second frequency divider divides the second output frequency by a dynamically variable second value to generate the final output frequency, wherein the final output frequency is a function of the reference frequency and a dynamically variable ratio relating the fixed first value to the dynamically variable second value.
