8 pin Dual-in-Line MIL SPECIFICATION
Page 1 of 2
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).
