ISOTEMP RESEARCH 434-295-3101, OCXO144Series

OCXO 144 SERIES
	The OCXO144 series oscillators are designed to be surface mounted using normal reflow soldering techniques. Frequency adjustment is by electrical means using a potentiometer or D/A converter. A convenient voltage reference source is available for this purpose. The units are available in ESD approved tape and reel or bulk packaging. Your choice of AT or SC cut resonators are available to meet your frequency stability requirements.
