HGXO OSCILLATOR
460 kHz to 50 MHz
High Shock Surface Mount Crystal Oscillator
DESCRIPTION
Statek’s HGXO crystal oscillator is an ultra-miniature,
surface-mount oscillator that can survive extremely high
shocks _ up to 100,000 g. The design consists of a
hermetically-sealed high-shock crystal and a CMOS
compatible integrated circuit housed in a 5.0 mm x 7.5 mm
surface-mount ceramic package.
FEATURES
Mechanical shock survivability up to 100,000 g
CMOS output, TTL on request
Optional Output Enable/Disable with Tri-State
Low EMI emission
Surface mount
Full military testing to MIL-PRF-55310 available
Hermetically sealed ceramic package
Low acceleration sensitivity available
SM1 and SM5 versions are Pb free

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 compares the
E and T versions.
