General Description
The CX-1 quartz crystal is a high quality miniature AT-cut
resonator. The CX-1 is hermetically sealed in a rugged, miniature
ceramic package, a quarter of 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.
 Low-profile hermetically sealed package
 Excellent ageing characteristics
 Fundamental or 3rd Overtone mode
 High shock resistance
 Full military environmental testing available
