OCXO-143
Features:
Typical 25.4 x 25.4 x 15.0 mm.
SC-Cut Crystal
High Stability; Low Phase Noise
CMOS//Sine Wave; Fast Warm-up
The OCXO 143 series oscillators are only one inch square and
designed for thru-hole mounting. These packages offer much
tighter frequency stability than TCXOs and in some cases cost
less. Frequency adjustment is by electrical means using a
potentiometer or D/A converter. A Convenient voltage
reference source is available for this purpose. Your choice of
AT or SC cut resonators are available to meet your frequency
stability requirements.

* 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 range is sufficient for the life of the oscillator specifications subject to change with frequency.
