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.
