SURFACE-MOUNT OSCILLATORS
XO95 SERIES
6.5mm x 5.0mm
High-Specification Oscillator
OUTLINES AND DIMENSIONS
DESCRIPTION
Euroquartz XO95 series oscillators consist of a TTL/CMOS compatible
hybrid circuit and a miniature quartz crystal packaged in a low-profile
ceramic package. Full military testing is available making this an ideal
crystal for defence and aerospace applications requiring a highly reliable
source of clock signals.
