Abstract:
Embodiments described herein provide a system having phase synchronized local oscillator paths. The system includes a first circuit, which in turn includes a first counter configured to generate a first counter output signal in response to a first clock signal controlling the first counter. The first circuit also includes a first phase-locked loop coupled to the first counter. The first phase-locked loop is configured to receive the first counter output signal as a first synchronization clock for the first phase-locked loop and to generate a first output signal having rising edges aligned according to the first counter output signal.
