HGXOHT OSCILLATOR - Statek Corporation

HGXOHT OSCILLATOR
32.768 kHz
High Shock, High Temperature Crystal Oscillator
DESCRIPTION
For high temperature, high stability and fast start-up
applications, Statek offers the AT crystal-based 32.768 kHz
HGXOHT oscillator. This oscillator is designed to operate at
temperatures up to 200OC. A high-shock version is also
offered that features 100,000 g shock survivability. Other
features include fast start-up time (0.8 ms typical) and low
current operation (500 µA at 25OC.)
FEATURES

ENABLE/DISABLE OPTIONS (E/N)
For the 32.768 kHz HGXOHT, Statek offers two
enable/disable options: E and N. The E-version has a TriState 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 so has no enable/disable
capability. The following table describes the Enable/Disable
option E.
