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.

Power Down: When Pad 1 is LOW (0) the oscillator stops
oscillation.
Tristate; When Pad 1 is LOW the oscillator continues to run but the
output buffer amplifier stops functioning; output is high
