OUTLINE & DIMENSIONS
DESCRIPTION
CXOMK oscillators are miniature, surface mount units packaged in a
6.5 x 5.0 x 1.5mm package. Ultilizing the latest advancements in
production technology, the CXOMK oscillator is capable of achieving
close tolerance frequency calibration and high stability over a wide
temperature range. High shock resistance. The part is available with
full 'MIL' testing if required.

COMPARISON OF ENABLE/DISABLE OPTIONS
There are three Enable/Disable options available, E, T and N. Both
the E and T versions have Tri-state outputs. In the E version the
oscillator stops, in the T version the oscillator continues to run. The N
version (no tristate function) does not have pin 1 connected internally.
