Abstract
Control circuitry for use in generating a local oscillator (LO) signal is provided. Synthesizer control circuitry is configured to control synthesizer circuity to generate an analog oscillator signal having a first frequency at which phase noise is minimized. DS control circuitry is configured to generate a control word or message to cause DS circuitry to generate a digital DS signal having a desired frequency when the DS circuitry is clocked by the oscillator signal having the first frequency. The desired frequency is proportional to the LO signal frequency. The digital DS signal generated by the DS circuitry is used to generate the LO signal. Thus the first frequency used to clock the DS circuitry is selected to optimize the oscillator rather than having some relationship to the LO frequency. In addition, a single synthesizer may be used in order to simultaneously generate many LO signals.
