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 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).
