HGXOHT OSCILLATOR
460 kHz to 50 MHz
High Shock, High Temperature Crystal Oscillator
DESCRIPTION
Statek’s HGXOHT crystal oscillator is a high temperature,
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
High temperature operation up to 200

ENABLE/DISABLE OPTIONS (E/N)
Statek offers two enable/disable options: E and N. The E-
version has a Tri-State 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 has no
enable/disable capability. The following table describes the
Enable/Disable option E.
