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.
