Abstract
A functional clock generator, including: an oscillator configured to generate an oscillator clock having an oscillator clock frequency; a control value generator configured to generate control values to ramp the oscillator clock frequency between a first frequency and a second, higher frequency; a Phase-Locked Loop (PLL) configured to generate a PLL clock having the second frequency; and a selector configured to switch between selecting the oscillator clock and the PLL clock as a functional clock when the oscillator clock frequency and the PLL clock frequency are substantially equal.
