LHGAT OSCILLATOR
Leaded Military Grade/High Shock
320 kHz - 50 MHz
DESCRIPTION
An increasing number of military applications require the use
of leaded (through hole) ceramic packaged oscillators. For
these applications, Statek offers the LHGAT 5x7mm
oscillator. This oscillator is designed to operate over a
temperature range of -55ºC to 125ºC with high shock
survivability.

ENABLE/DISABLE OPTIONS (E/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.
