Patent ID: 10958277

Abstract:
This application is directed to an electronic device including a phase locked loop (PLL) circuit. The PLL includes a voltage-controlled oscillator (VCO) and the PLL is configured to generate a plurality of periodic signals having a first frequency. Optionally, the periodic signals are equally separated in phase to cover an entire period cycle of the first frequency. The electronic device includes a first multiplexer coupled to the PLL, the first multiplexer being external to the PLL. The first multiplexer configured to receive a first selection signal, select a first periodic signal of the plurality of periodic signals based on the first selection signal, and provide the first selected periodic signal to a first clock-driven circuit that is distinct from the PLL. The electronic device further includes a controller circuit coupled to the first multiplexer, the controller circuit being configured to provide the first selection signal to the first multiplexer.
