General Description
The CX-2V quartz crystal is a high quality tuning fork resonator
designed for use in Pierce (single inverter) oscillators. The CX-2V is
hermetically sealed in a rugged, miniature ceramic package, a
quarter the size of an eight pin dual-in-line package. The crystal is
manufactured utilizing a photo-lithographic process, ensuring
consistency and repeatability of electrical characteristics.
