STATEK CX9

CX9 TELEMETRY CRYSTAL
14 MHz to 250 MHz
Low Profile, Ultra Miniature
Surface Mount AT Quartz Crystal
DESCRIPTION
Designed and manufactured in the USA, the CX9 family of
medical RF telemetry crystals provide the widest frequency
range for this application. Using micro-machining processes,
this surface mount crystal is hermetically sealed within an
ultra miniature ceramic package to ensure high stability and
low aging. Small size, tight calibration and excellent
frequency/temperature stability make the CX9 telemetry
crystal ideally suited for medical applications.

1. Other tolerances available. Contact factory.
2. Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the AT thickness-shear mode.
3. 5 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher frequencies
contact factory.
4. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
Per EIA 481 (see Tape and Reel data sheet 10109)
