ABSTRACT:
A method for controlling a synthesized local oscillator (SLO) includes: receiving a control input specifying a desired SLO output; receiving reference clock signal; generating a predefined set of dynamic clock signals from the reference clock signal; selecting a dynamic clock signal from the predefined set of dynamic clock signals in response to the control input; using the dynamic clock signal as an input to a direct digital synthesizer (DDS) module to generate a DDS output signal; selecting a DDS output band in response to the control input, the DDS output band including one of a baseband and an alias band; and processing the DDS output band to generate the SLO output.
