CMOS//Sine Wave output; Fast Warm-up
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.

* All aging stabilities are after storage of up to one year and apply after 30 days of continuous operation.
The daily aging rate also applies at the time of shipment from factory.
** The electronic frequency adjustment rage is sufficient for the life of the oscillator specification subject to change with frequency.
