CXO OSCILLATORS  
Low Profile Miniature SMD Crystal Oscillator  
300kHz to 170MHz  
FEATURES  
Frequency Range 300kHz to 170MHz  
Supply voltage from 0.9V to 5.0Volts available  
Full 'MIL' testing available  
OUTLINE & DIMENSIONS

DESCRIPTION  
CXO oscillators consist of a miniature quartz crystal and a CMOS/TTL  
compatible hybrid circuit in a low-profile, small footprint ceramic  
package. In addition to the conventional solder or epoxy electrical  
connection techniques, the CXO oscillator's bond pads on the topside  
of the unit allow it to be connected electrically in a hybrid assembly  
using wire bonds.  
SPECIFICATION  
Specifications are typical at 25°C unless otherwise indicated. Tighter  
specifications are available, contact Euroquartz technical sales.
