General Description
The CX-2 AT-cut quartz crystal is a high quality, miniature
resonator, hermetically sealed in a rugged, miniature ceramic
package, a quarter the size of an eight pin dual-in-line. The CX-2
crystal is manufactured utilizing a photo-lithographic process,
ensuring consistency and repeatability of electrical characteristics.
