ABSTRACT:
A method and apparatus are provided for generating a ratioed clock signal. A first clock signal having a first frequency is output. At least one gating signal indicating ratio is output. In response to the first clock signal and the gating signal, a second clock signal is output. The second clock signal has a frequency that is substantially related to the first frequency by the ratio.
