CXOL OSCILLATOR
32 kHz - 100 kHz
Ultra-Low Current, Miniature Quartz Crystal Oscillator
DESCRIPTION
CXOL is an ultra-miniature (3.2 x 1.5mm), ultra-low current
quartz crystal oscillator with a typical start-up time of
200ms. Hermetically sealed in a highly reliable ceramic
housing, this oscillator is available over a wide range of input
voltages (1.2 V - 5.0 V).
FEATURES
Ultra-low current consumption
Typical start-up time of 200ms
Typical rise and fall times of 25ns
Hermetically sealed ceramic package
Optional output enable/disable with Tri-State
Full military testing per MIL-PRF-55310 available
Designed, manufactured, and tested in the USA

Statek offers two enable/disable options: T and N. The T-
version has a Tri-State output and continues 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 Tri-State/Disable capability. The following table
describes the Tri-State/Disable option T.
