OUTLINE & DIMENSIONS
DESCRIPTION
CXOL oscillators are ultra-miniature (32. x 1.5mm), ultra-low current
quartz crystal oscillators with a typical start-up time of 200ms.
Hermetically sealed in a highy reliable ceramic housing, these
oscdillators are available over a wide range of input voltages (1.2V ~
5.0V).

ENABLE/DISABLE OPTIONS
There are two Enable/Disable options available, 'T' and 'N'. The 'T'
version has a Tri-State output and continues oscillating internally
when the output is put into a high Z state. The 'N' version does not
have PAD 3 connected internally and so has no Tri-State capability.
The table below describes the Tri-State option 'T':

When Pad 3 is allowed to float it is held high by an internal
pull-up resistor.
PACKAGING OPTIONS
CXOL oscillators are available either tray packed (<250pcs) or tape
and reel (>250 pieces).
12mm tape, 178mm or 330mm reels (EIA 418).
