Thanks, Jack. This was my opinion as well, but I've heard and seen others claiming just the opposite, In the case of my equipment we have a 125 MHz clock that is PLL'd up to 1.25Ghz for some optics. I have always tested to 6.5 GHz, but even though it seems clear I've had dissenting discussions. Thanks Gary

Here it is, from the table in para. 15.33 (4). "Highest frequency generated or used in the device or on which the device operates or tunes (MHz)" It doesn't appear to concern itself with *how* the signal is generated (ocillator, PLL, etc.) or whether it's a fundamental or not. So, it seems clear enough to me. Or maybe I'm missing something.
