ABSTRACT:
A secondary clock generator circuit is described in which a ratio is programmed into circuitry which will be embedded on all components. The programmable circuitry takes the system's master clock signal multiplies it by the programmed ratio and yields a secondary clock signal equal to the ratio times the master clock signal for driving components and interfaces. The invention is particularly useful in computer systems operating at a first clock frequency which have replaceable components that run at different clock frequencies and where it is desired to provide a synchronization between the system clock and the various component clocks.
