DESCRIPTION
CXOX oscillators are 32.768kHz, ultra-miniature, surface mount units
packaged in a 3.40 x 2.50 x 1.12mm package. The oscillators have
been designed to provide a fast start-up time with tight frequency
stability over a wide operating temperature range of -55° to +125°C.
The design of the part ensures there is a significantly greater ability to
withstand significantly higher shock levels than standard tuning fork
crystal designs.
SPECIFICATION
Specifications are typical at 25°C unless otherwise indicated. Tighter
specifications are available, contact Euroquartz technical sales.

ENABLE/DISABLE OPTIONS
over Operating Temperature Range
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.
