摘要： A digital PLL may be combined with an analog PLL so that the output of the digital PLL is at a frequency high enough to maintain stability in the analog PLL when an initial reference clock signal is too low to maintain stability in the analog PLL. The digital PLL may include a scaling circuit, such as a frequency divider in the feedback path of the PLL, to generate the higher frequency output signal from the lower frequency reference input signal. The digital PLL may also use an on-chip free run ring oscillator as the clock for the digital PLL engine.
