EURO QUARTZ EQXO-2000BM OSCILLATORS 8 pin Dual-in-Line MIL SPECIFICATION 30kHz to 70MHz Page 1 of 2 FEATURES * Ceramic substrate and ruggedized mounts for high reliability Industry-standard 8 pin DIL package for ease of design Full screening to MIL-O-55310C, Class B available Radiation tolerant version favailable for space applications 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).
