| OCXO 131 SERIES | |
|---|---|
 |
The OCXO 131 series oscillators feature small European style packages designed for applications where space is at a premium and good frequency stability is required. The oscillators can be used in phase locked loops or as stand alone references in many communications applications such as Stratum 3 switching apparatus or cellular telephone base stations. An internal voltage reference is provided to make frequency corrections via a simple potentiometer or may be used as a voltage source for a digital to analog converter. The package is a hermetically sealed through hole printed circuit board mount. A choice of quartz resonators offers a variety of performance versus cost options to fit most applications. |
