OUTLINE & DIMENSIONS
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.

ENABLE/DISABLE OPTIONS
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.

When Pad 1 is allowed to float it is held high by an
internal pull-up resistor.
PACKAGING OPTIONS
CXOQ oscillators are available either tray packed (<250pcs) or tape
and reel (>250 pieces).
12mm tape, 178mm or 330mm reels (EIA 418).
