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.
