General Description
The CX-1H quartz crystal is a high quality tuning fork resonator
designed for use in Series (two cascaded inverters) oscillators. The
CX-1H 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.
