SURFACE-MOUNT OSCILLATORS
XO95 SERIES
6.5mm x 5.0mm
High-Specification Oscillator
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.

Tristate; When Pad 1 is LOW the oscillator continues to run but the
output buffer amplifier stops functioning; output is high
