Abstract

An on-die clock generator. For one aspect of the invention, the on-die clock generator includes a phase-locked loop (PLL) circuit having a first input coupled to receive an external clock signal and an output coupled to provide an on-die clock signal to be used during a normal operating mode of an integrated circuit. The on-die clock generator also includes a local clock generator circuit having an input coupled to receive the on-die clock signal and an output coupled to provide a local PLL feedback clock signal to a second input of the PLL.
