| OCXO 82 SERIES | |
|---|---|
 |
The OCXO 82 series oscillators are currently our most popular models because of the price and performance options available. The package is a hermetically sealed printed circuit board mount with optional chassis mounting upon request. Applications include telecommunications products such as Stratum 3 and 3E clocks as well as base station frequency references for Cellular, CDMA, TDMA, GSM, and Paging. Other uses include GPS navigation and instrumentation. |
