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

phased 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.
