I realize that the specs say that the max is 100MHz, due to its internal 200MHz VCXO being only divisible by 2 or higher. But is there a hard limit on max frequency from an externally provide clock? For example, what if an external clock is fed in at 105MHz? I'm guessing the official answer is no, but I'm interested to find out if basic functionality actually goes a bit beyond the official/guaranteed specs. Thanks for your help.
