RK115
This high reliability XO RK115 is designed for space applications and is based on hybrid technology, where it is resistant to extreme
environments (Radiation, shock and vibration). The key advantages of this oscillator are low power consumption and short lead times. The
RK115 is available with the second generation of enhanced J‐lead technology which make its report easy and is also available in Flatpack and
DIL packages, pin‐to‐pin compatible with most of the Space XOs in the market.
