Abstract:
In some embodiments, an integrated circuit may include a radio frequency synthesizer configured to provide a local oscillator (LO) signal at a selected frequency related to a frequency of interest. The integrated circuit may also include a re-clocking circuit having a first input to receive a clock signal having a first frequency, a second input to receive a local timing signal related to the LO signal, and an output. The re-clocking circuit may be configured to provide a local timing output signal that is a frequency adjusted version of the clock signal based upon the local re-clocking signal. The integrated circuit further may include a digital circuit including an input to receive the local timing output signal as a digital clock signal in a receive mode.
