DESCRIPTION
HGXO oscillators are miniature, surface mount units that can survive
extremely high shocks, up to 100,000g. The design consists of a
hermetically-sealed high shock crystal and a CMOS compatible
integrated circuit housed in a SMD 7.5mm x 5.0mm ceramic package.
Designed and manufactured in USA by Statek Inc.

PACKAGING OPTIONS
HGXO oscillators are available either tray packed (<250pcs) or tape
and reel (>250 pieces).
* When Pin 1 is allowed to float it is held 'high' by an internal pull-up
resistor.
16mm tape, 178mm or 330mm reels (EIA 418).
Option 'N' = Pin 1 not connected internally.
