Abstract

A method and apparatus are provided for generating a phase-controlled clock signal within a microprocessor. A first clock signal having a first frequency is input. After a reset event, the first clock signal transitions in a first direction at a time t. A second clock signal is output having a second frequency related to the first frequency by a non-integer ratio. The second clock signal transitions in the same direction as the first clock signal at time t.
