than 500 kHz.
clock frequency (spread spectrum clock generators). In no cases can the AMD processor system bus period violate
the minimum specification above. AMD processor system bus clock inputs can vary from 100% of the specified fre-
quency to 99% of the specified frequency at a maximum rate of 100 kHz.
