Abstract: There is provide a system comprising a plurality of receivers, each receiver comprising a local oscillator configured to generate a local oscillation signal, a primary mixer configured to mix an input signal with a reference signal at a reference frequency to generate a first output signal, a divider configured to divide the reference signal into a second reference signal at a second frequency and a secondary mixer coupled to the primary mixer and configured to mix the first output signal and the second reference signal at the second frequency. In a first mode, the reference signal for a first of a plurality of the receivers is the local oscillation signal from the first receiver and, in a second mode, the reference signal is the local oscillation signal from another of the plurality of receivers.

Abstract: A method for providing a reference clock signal, comprising: generating, by an oscillator, a first clock signal having a first frequency, the first clock signal being coupled to a frequency synthesizer; generating, by the frequency synthesizer, a second clock signal based on the first clock signal, the second clock signal having a second frequency different from the first frequency; outputting a reference clock signal to one or more components of an electronic device, the reference clock signal being one of the first clock signal or the second clock signal; identifying one or more spurious frequency components; and monitoring the reference clock signal for a presence of the one or more spurious frequency components, the monitoring comprising: in response to determining the presence of at least one of the one or more spurious frequency components, selecting a different one of the first clock signal or the second clock signal to be the reference clock signal.
