Abstract
Switching a clocked device from an initial frequency to a target frequency includes locking a first phase locked loop (PLL) to the target frequency while a second PLL is driving a clock distribution network at the initial frequency. The first PLL is then substituted for the second PLL on the clock distribution network.
