6. Radiation
The oscillator is capable of meeting all electrical performance requirements after exposure to a total ionizing
dose (TID) of 10 krad(Si). The radiation performance will be verified by a radiation test (Co 60).
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 are commercial off-the-shelf (COTS) versions. Capacitors are compliant with
the requirements of AEC-Q200.
The quartz crystal has 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).
No pure tin is used inside the oscillator, as package or lead finish.
The printed circuit board (PCB) is commercially procured.
The marking is resistant to Zestron VD, Isopropyl alcohol (99% pure) and Ethyl alcohol (99.5% pure),
tested in accordance with ESCC24800.
8. Marking
The marking of the parts is accordance with ESCC21700. The content is as follows:
(1) Company Logo AXTAL
(2) Part number AXTAL (according to order code)
(3) Part number Customer (on request)
(4) Nominal frequency
(5) Serial number
(6) Date Code

10. Handling, Packaging and Delivery
Some add-ons are susceptible to damage by electrostatic discharge. Therefore suitable ESD
precautions for handling during use and manufacturing must be employed.
In order to minimize the risk of damage, all kinds of shock during handling and manufacturing must be
avoided.
The parts are packaged in a way to ensure adequately safeguarding against mechanical and electrical
injury and deterioration due to humidity.
The primary package is labeled as ESD sensitive component.
