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 can be verified by a radiation test (Co 60) on request.

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 high Q quartz material

with low inclusion density and low etch channel density (according to IEC 60758).

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
