OUTLINE & DIMENSIONS  
DESCRIPTION  
EQXO-2000BM series oscillators are designed and manufactured by  
Euroquartz Ltd for aerospace, defence and similar applications where  
high-reliability clock oscillators are required. The oscillator is produced  
in the industry-standard 8 pin DIL oscillator package. EQXO-2000BM  
series oscillators incorporates a custom designed, all-ceramic  
oscillator substrate and a ruggedized three-point crystal mounting  
system inside a hermetically-sealed metal package. The specification  
ensures that EQXO-2000BM series oscillators provide an accurate and  
reliable source of clock signals regardless of the severity of the  
environment in which it operates.  
RADIATION TOLERANCE  
For equipment to be used in space or the upper atmosphere the  
EQXO-2000BM series oscillators may be produced in a radiation  
tolerant version. Designated EQXO-2000BMH, this variant of the  
oscillator will withstand ionizing radiation to resist electrical failures  
for a total radiation dose of 40krad(SI).

MIL SCREENING  
EQXO-2000BM series oscillators may be ordered screened  
i.a.w. the schedules detailed in 'Qualification Approval and  
Environmental Specification' on page 2 of this specification.  
* Frequency stability is inclusive of frequency adjustment at 25°C and  
any variations due to load change, ageing, supply voltage change  
(±10%) and variations attributable to shock and vibration, (see  
Qualification Approval and Environmental Specification.)
