Abstract
A system and method are provided for synthesizing signal frequencies using a single reference clock and a primitive ratio of integers. The method accepts a plurality (k) of reference frequency values (f), where 1≦i≦k, associated with a corresponding plurality of synthesized frequency values (f). For each synthesized frequency value, a raw ratio of integers Npand Dpis calculated, such that: A greatest common divisor (GCD) of Npand Dpand a primitive ratio of integers is found for each raw ratio of integers, such that: Using the common clock frequency value (f), each primitive ratio of integers, each reference frequency value, and each GCD, a final ratio of integers Nand D, is calculated for each synthesized frequency value, where C is an integer value.
