I want to use this clock oscillator
It does not require loading capacitance.
However, it says "3.3V operation (optional)", yet on the same page it says "Supply Voltage: 5VDC +/- 0.25".
I was considering just throwing it in a breadboard, giving it 3.3V, and scoping the output pin to see if it worked. But I was wondering if I would have any problems since the output pin would be unloaded, except for the scope.
