Product Description
This MIL-PRF-55310 level Space XO is designed for space applications and is based on hybrid
technology.
The reference is resistant to shock and vibration environment.
Key advantages of this frequency source are low power consumption, its availability in different packages (J-lead,
Flat Pack, DIL), its short lead time and its high resistance to heavy ions.
nd
The availability of the enhanced J-lead package (2 generation of J-lead package) makes its report easier.
This XO is manufactured in accordance with MIL-PRF-55310 (Class 2, type 1, level S).
