EQXO-1000BM and 3000BM OSCILLATORS  
14 pin Dual-in-Line MIL SPECIFICATION

FEATURES  
OUTLINE & DIMENSIONS  
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).
