Abstract
A phase-locked loop (PLL) circuit includes multiple selectable feedback paths and a mode selector for selecting different feedback paths in different operating modes. The PLL circuit may correct for clock skew or produce a desired degree of clock skew between input and output clock signals in different operating modes.
