Morphology

crystal + oscillator

The noun–noun compound is compositional: 'crystal' modifies 'oscillator', so a learner who knows 'crystal' (a piece of quartz) and 'oscillator' (a device that produces periodic waves) can infer it is an oscillator that uses a crystal. Technical specifics about piezoelectric resonance and precise frequency are specialist, but the core meaning is directly derivable from the constituents and common compound patterns.

Etymology

Crystal oscillator comes from a small crystal of quartz that vibrates like a tiny tuning fork, and an oscillator is something that makes a regular back-and-forth movement. Electronics use that steady vibration as a 'precise frequency' or a steady beat to 'keep time' and control other parts, so the name explains why it gives a very steady signal.
