Abstract:
According to some embodiments, an apparatus for generating multiple variable frequency and phase locked clock signals comprises complex tuners, digital up-samplers, image isolation filters, quadrature modulators, a combiner, a DAC, a local oscillator, and an analog filter. The complex tuners tune multiple digital baseband signals. The up-samplers interpolate the complex tuned digital signals such that one of the up-sampled images of each of the complex tuned digital signals corresponds to a desired frequency. The image isolation filters isolate images corresponding to the desired frequencies. The quadrature modulators convert the isolated images of the complex tuned digital signals into real digital signals. The combiner combines the real digital signals into a combined real digital signal. The DAC, driven by the local oscillator, converts the combined real digital signal into an analog clock signal. The analog filter then filters the analog clock signal to select images located at the desired frequencies.

Claim (Index 8):
A method of generating variable frequency clock signals, comprising:\n performing complex tuning on a first digital baseband signal to produce a first complex tuned digital signal translated in the frequency domain; performing complex tuning on a second digital baseband signal to produce a second complex tuned digital signal translated in the frequency domain; interpolating the first complex tuned digital signal by N to create N equally spaced images in the frequency domain, one of the N images corresponding to a first desired frequency; interpolating the second complex tuned digital signal by M to create M equally spaced images in the frequency domain, one of the M images corresponding to a second desired frequency; isolating the one of the N images of the first complex tuned digital signal that corresponds to the first desired frequency using a first image isolation filter; isolating the one of the M images of the second complex tuned digital signal that corresponds to the second desired frequency using a second image isolation filter; performing quadrature modulation to convert the isolated image of the first complex tuned digital signal into a first real digital signal; performing quadrature modulation to convert the isolated image of the second complex tuned digital signal into a second real digital signal; combining the first real digital signal and the second real digital signal into a combined real digital signal; and converting the combined real digital signal into an analog clock signal using a digital-to-analog converter (DAC), wherein the DAC is driven by a local oscillator.
