OXK581 series Low phase noise,Anti-vibration OCXO

Note: The following phase noise are the worse one among three axis at 1KHz offset frequency

Phase noise vs. Offset frequency @120MHz/Random

RMS acceleration G =11.95 g

rms

RMS acceleration G =9.26 g

vibration method D

Note

1.No less than 1uF electrolytic capacitor and 0.01～0.1uF ceramic capacitor are recommended to be used on

power supply.

2.Vibration absorptive material can be used outside OCXO to improve phase noise performance under vibration

3.See package section for detial information of outline drawings.

1.In phase noise performance curve, the upper curve is the performance under vibration

the lower one is under static.

2.All phase noise curves showed above are the worse one of three axis at 1KHz offset frequency

3.Phase noise performance depend on vibration method, please give your method when order.
