I have got one of those small crystals, packed in a silver package, low-profile, two pins. How do I connect it so that I get the output that is printed on it (7,680)?
It sounds like you are looking for an AC output at the crystal frequency so the crystal is only part of an oscillator. Crystals can also be used in filters.
w00t!? Don't they need power or anything? Just the crystal, a resistor and an inverter gate, and then I get my square 7,68Khz output?? That looks way too simple and mystic!

What would they need power for? THink of it.. it is just a piece of.. well crystal. There are no active circuits involved inside the crystal. The output power avalilable from the oscillator (not xtal) is from the inverters that sebi has shown.
A crystal by itself is a passive device of sorts. It only reacts to a stimulation input.
