I was looking through standards I have but can't find an absolute description of highest clock frequency. The overall device has clocks well below 105MHz, the point at which the spectrum above 1 GHZ must be investigated during radiated emissions. However one of the IC's has an internal frequency well above that. My understanding of highest clock would include this IC internal, contained within the chip and not provided to any I/O pins. Others disagree, but I can't find any explicit documentation that defines this. Can anyone pin point a textual definition?
