DESCRIPTION
XO95 oscillators consist of a TTL/CMOS-compatible hybrid circuit
with a miniature quartz crystal packaged in a low-profile, ceramic
package. The combination of optimized design and high quality
materials provide a highly reliable clock oscillator suitable for defence
and aerospace applications.
APPLICATIONS
Military & Aerospace
Smart munitions
Cockpit Systems
Navigation
Engine control systems
Industrial, Computer & Communications
Industrial controls
Instrumentation
Microprocessor clocks
ENABLE/DISABLE OPTIONS (E/T/N)
Medical
XO95 oscillators are offered with three enable/disable options: E, T
and N. Both the E and T versions have Tri-State outputs and differ in
whether the oscillator continues to run internally when the output is
in put into the high Z state: In the E version the oscillator stops when
disabled while in the T version the oscillator continues to run when
disabled. Hence, the E version offers very low current consumption
when disabled and the T version offers very fast output recovery
when the oscillator is re-enabled. The N version does not have Pad 1
connected internally so has no enable/disable function. the following
table summarizes the three options:
