CXOX OSCILLATOR
32.768 kHz
Fast Start-up/Tight Tolerance/High Shock
DESCRIPTION
Designed for applications requiring a fast start-up time
(0.6 ms) and a tight frequency stability (± -30 to ± -100 ppm)
over a wide temperature range (-55 C to +125 C). They
are also capable of withstanding significantly higher shock
than a standard tuning fork design.

ENABLE/DISABLE OPTIONS (E/N)
For the 32.768 kHz CXOX, Statek offers two
enable/disable options: E and N. The E-version has a TriState output and stops oscillating internally when the
output is put into the high Z state. The N-version does not
have PIN 1 connected internally and so has no
enable/disable capability. The following table summarizes
the Enable/Disable option E.
