DESCRIPTION
CXOQ oscillators are ultra-miniature, surface mount units packaged
in a 2.50 x 2.00 x 0.89mm package. The oscillators are capable of
withstanding high shock environments. The design and build standard
including availability of full 'MIL' testing ensures great reliability.

There are two Enable/Disable options available, 'E' and 'N'. The 'E'
option stops oscillating when the output is put into the High Z state.
the 'N' version does not have Pad 1 connected internally. the table
below describes the 'E' Enable/Disable option.
