Ordering Information
CMOS output
Product name + variant + option codes + frequency
eg: GHTXOL 24.00MHz 3.3V supply, no E/D
GHTXOS/E 20.0MHz 5.0V supply, E/D function
Option code X (eg GHTXOL/X) denotes a custom spec.
Miniature SM package
Excellent frequency stability
 1: Relative to nominal frequency
 2: Expected life at 250°C is 1000 hours minimum
 3: A bypass capacitor 0.1μF should be connected as close as possible
to supply and ground pads
Oil and gas downhole instrumentation
