crystals
(6 products)
These are most commonly used with PICs or other micro-controllers as a clock source.
oscillators
(2 products)
These perform a similar function to crystals, except they require no additional circuitry to provide a square output wave, just power. This means they won't depend on the accuracy of external capacitors or stray capacitance on the board. Their downside is that they draw more current and cost more.
