Radiation
Radiation testing is not performed, but these VCXOs have been acceptable for use in
environments up to 100K rads by analysis of the components used. They are
assembled with all bipolar semiconductors with the exception of the ACMOS chip
used for the CMOS output which is purchased from a wafer that has been tested to a
minimum of 100K rads total dose. A copy of the parts list and materials can be
provided for review.

FREQUENCY STABILITY and
FREQUENCY DEVIATION OPTIONS
These limits guarantee that under the worse case conditions of temperature, supply voltage, load stability
and 10 years aging, that the oscillator can be pulled back on to nominal frequency with the Control
Voltage function.
