Crystal or Oscillator: Choosing the Clock Source
A crystal needs a circuit; an oscillator is a part. Accuracy classes, startup, jitter, what changes on the board, and when a resonator is enough.

Supply boundary
Product records help identify a manufacturer part number and technical family. A listed part may be fulfilled from Chip-seek warehouse-held stock or a reviewed sourcing channel. Source, quantity, packaging, date code, MOQ, price and lead time are confirmed before an order is accepted.
