General Description
The miniature CX-1H-SM quartz crystal is a high quality tuning-
fork resonator for use in series (two cascaded inverters) oscillators.
The CX-1H-SM is hermetically sealed in a rugged, leadless
ceramic package. The crystal has been designed for surface-
mounting on printed circuit boards or hybrid circuits. The CX-1-SM
crystal is manufactured using a photo-lithographic process,
yielding consistently high quality production parts.
