General Description
The CX-2 quartz crystal is a high quality extensional mode
resonator. The CX-2 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.
