OCXO 126 SERIES
	The OCXO126 series oscillators offer the end user a variety of options including separate oven and oscillator voltages, lower output frequencies, and different pin out patterns. The larger style package allows room for dividers and filters in the output stages and the separate voltages allow the user to conserve power by using an unregulated supply for the oven circuit.
