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.

Circuit Design
Typical HCMOS Pierce Oscillator
A conventional HCMOS Pierce oscillator is shown below. The crystal oscillates at a frequency f above the crystals seriesresonant frequency. The crystal is effectively inductive and in combination with R , C and C in the feedback loop, provides approximately 180 of the phase shift necessary to ensure oscillation.
