STATEK CXOLAT

CXOLAT OSCILLATOR
32.768 kHz
Ultra-Low Power/Fast Start-Up/Ultra-Miniature
DESCRIPTION
The CXOXLAT 32.768 kHz oscillator achieves the low
power comparable with a tuning fork design and the fast
start-up and tight frequency stability attained by an AT cut
crystal design. Designed for applications requiring ultralow current (15 µA), fast start-up time (15 ms), and a tight
frequency stability (±30 ppm to ±100 ppm) over a wide
temperature range (-55OC to +125OC). These oscillators
are also capable of withstanding significantly higher
shock than a standard tuning fork design.

ENABLE/DISABLE OPTIONS (E/N)
For the 32.768 kHz CXOLAT, 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 3 connected internally and so has no
enable/disable capability. The following table summarizes
the Enable/Disable option E.
