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.)

RADIATION TOLERANT VERSIONS

Radiation tolerant versions of EQXO-2000BM series oscillators have

been designed and are manufactured to ensure no functional failures

will occur in any electrical test for a total radiation dose of 40krad(Si).

EQXO-2000BM series oscillators so manufactured have the letter 'H'

appended to the 'BM' in the part number suffix:

20.000MHz EQXO2100BMH

A paper is available describing the general problems encountered in

the design of electrical systems needing to withstand radiation

encountered in the upper atmosphere and space.
