Patent ID: 7602254

Claim:
A circuit for generating multiple output signals, comprising: a first-stage frequency conversion block comprising a first-stage input signal and a first-stage output signal, wherein a frequency of the first-stage output signal is a preselected ratio of a frequency of the first-stage input signal; and a plurality of second-stage frequency conversion blocks, each comprising a second-stage input coupled to the first-stage output signal, and each second-stage frequency conversion block transmitting a second-stage output signal, wherein a frequency of the second-stage output signal is a preselected ratio of the frequency of the first-stage input signal and wherein a frequency of the second-stage input signal is higher than the frequency of the first-stage input signal; dividers coupled to the second-stage output signals, wherein the dividers divide a frequency of a selected second-stage output signal; and one or more multiplexers coupled to outputs of the dividers.
