DESCRIPTION

EQXO-1000BM and 3000BM 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 14 pin DIL oscillator

package. EQXO-1000BM 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 the oscillators provide an

accurate and reliable source of clock signals regardless of the severity

of the environment in which it operates. EQXO-3000BM series

oscillators are identical to EQXO-1000BM series but have 14 pins for

extra mechanical security.

RADIATION TOLERANCE

For equipment to be used in space or the upper atmosphere the

EQXO-1000BM and 3000BM series oscillators may be produced in a

radiation tolerant version. Designated EQXO-x000BMH, this variant of

the oscillator will withstand ionizing radiation to resist electrical

failures for a total radiation dose of 40krad(SI).

RADIATION TOLERANT VERSIONS

Radiation tolerant versions of EQXO-1000BM 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-1000BM series oscillators so manufactured have the letter 'H'

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

20.000MHz EQXO-1100BMH

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.
