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.
OUTLINE & DIMENSIONS
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).
