| EURO QUARTZ FEATURES EQXO-1000BM and 3000BM OSCILLATORS 14 pin Dual-in-Line MIL SPECIFICATION OUTLINE & DIMENSIONS Page 1 of 2 * Ceramic substrate and ruggedized mounts for high reliability Industry-standard 14 pin DIL package, 4 pin or 14 pin Full screening to MIL-O-55310C, Class B available Radiation tolerant version favailable for space applications 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 threepoint 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.
