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 12):
An apparatus for generating variable frequency clock signals, the apparatus comprising:\n a complex tuner configured to tune a digital baseband signal to produce a complex tuned digital signal translated in the frequency domain; a digital up-sampler configured to interpolate the complex tuned digital signal by N to create N equally spaced images in the frequency domain, one of the N images corresponding to a desired frequency; an image isolation filter configured to isolate the one of the N images of the complex tuned digital signal that corresponds to the desired frequency; a quadrature modulator configured to convert the isolated image of the complex tuned digital signal into a real digital signal; a digital-to-analog converter (DAC) configured to convert the real digital signal into an analog clock signal; a local oscillator configured to drive the DAC; and an analog filter configured to filter the analog clock signal to select an image located at the desired frequency.
