- Do we still use piezo to power clock circuits of modern computers?by sixothree
- no, we use atomic clocks now... j/k
piezoelectric refers to generation of electricity from pressure applied to the material... the inverse of that effect is what generates oscillation.. quartz has a natural resonant frequency determined by its shape, size, and the way it’s cut, and when you apply AC it oscillates at a specific frequency.. the applied electricity causes is the material to deform.. that is the basic physical effect used in oscillators
MEMS oscillators are increasingly replacing quartz in compact, rugged, or integrated designs.
PLL-based frequency synthesis is used to scale a low-frequency reference (e.g., 25 MHz crystal) up to CPU/GPU GHz speeds.
- Obligatory must watch old dod training film on the subject.

- I wish people still talked with the accent/style used in these old videos. It's so easy to understand and listen to, compared to the typical modern American accent.by mikkupikku
