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).
