时钟信号基于定时的噪声抑制

Clock signal timing-based noise suppression
Abstract:
A method includes generating one of a first clock signal and a second clock signal from the other clock signal. The first clock signal is configured to be used to synchronize an operation of an analog system, and the second clock signal is configured to be used to synchronize an operation of a digital system. The method includes using a phase detector of the analog system to measure a timing of the first clock signal relative to the second clock signal; and the method includes controlling a delay element of the digital system to regulate the timing based on the measurement by the phase detector to suppress noise in the analog system.
