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.
