6. Radiation

The oscillator is capable of meeting all electrical performance requirements after exposure to a total ionizing

dose (TID) of 100 krad(Si). The radiation capability was verified by a radiation analysis in accordance with

ECSS-Q-HB-30-01A.

7. Components, Materials and Processes

The FM and LAT models are built on the basis of the following requirements for components, materials and

processes:

All add-on components and materials are compliant with the requirements of ECSS-Q-ST-60C.

All active components and the quartz crystal have a hermetically sealed package.

All active components are radiation tolerant. The crystal is made of synthetic swept quartz material.

Soldering is done by ESA approved personal in accordance with ECSS-Q-ST-70-08C (manual soldering)

and ECSS-Q-ST-70-38C (surface mount and mixed technology).

All used materials are in accordance with ECSS-Q-ST-70-71A. The lead material and finishes are

according to ESCC23500. No pure tin is used inside the oscillator, as package or lead finish.

The printed circuit board (PCB) is procured in accordance with ECSS-Q-ST-70-11C.

The marking is resistant to Zestron VD, Isopropyl alcohol (99% pure) and Ethyl alcohol (99.5% pure),

tested in accordance with ESCC24800.
