HFXO OSCILLATOR
220 kHz to 100 MHz
High Precision & High Shock,
Low Profile Miniature
Surface Mount Crystal Oscillator
DESCRIPTION
Statek’s high shock HFXO oscillators, available in tight
frequency tolerances, consist of a Statek miniature quartz
crystal and a CMOS/TTL compatible hybrid circuit in a
ceramic package. Each crystal used in the HFXO oscillator is
pre-qualified before assembly through electrical tests and
characterization over temperature.
FEATURES
Mechanical shock survivability of 75,000 g up to 50 MHz
Tight frequency tolerance
Low acceleration sensitivity
Low aging (Double Hermetic Seal)
Low jitter
Optional Output Enable/Disable with Tri-State
Low EMI emission
Full military testing to MIL-PRF-55310 available
Low power consumption

ENABLE/DISABLE OPTIONS (E/T/N)
Statek offers three enable/disable options: E, T, and N.
Both the E-version and T-version have Tri-State outputs and
differ in whether the oscillator continues to run internally
when the output is put into the high Z state: it stops in the
E-version and continues to run in the T-version. So, the E-
version offers very low current consumption when the
oscillator is disabled and the T-version offers very fast output
recovery when the oscillator is re-enabled. The N-version
does not have PIN 1 connected internally and so has no
enable/disable capability. The following table summarizes the
three options.
