Description
The SATCOM and "1 ppm Forever" series of
Temperature Compensated Crystal Oscillators
(TCXO's) are available in frequencies from
0.5 MHz to 160 MHz.
These series offer performance for short term
stability, phase noise, G sensitivity, aging and
temperature stability normally only associated
with Oven Controlled Crystal Oscillators
(OCXO's), while consuming typically < 20 mA.
With over 500,000 units produced, Vec-
tron International has more experience with this
type of TCXO then the rest of the industry
combined.

Note: Not all stabilities are available with all options. Vectron International does not recommend wave
soldering, IR reflow or other elevated temperature processing without consulting the factory.
For AC, HC and TD outputs with frequencies above 30 MHz a low phase noise PLL multiplier will be used.
Please inform the factory of your phase noise requirements.

Note: Temperature stabilities listed on the website are for the best possible stability in that series. Next to
quantity, Frequency vs. Temperature is the highest cost multiplier. Please do not over specify temperature
stability as we will 100% test units to your requirements. The temperature ranges listed above are industry
standards. However, if for example your requirements were for -33 to +55C please let us know, by choosing
-40 to +85C arbitrarily you will be paying more than is required. Custom stabilities are always welcome and
recommended. We do not charge extra for custom temperature ranges or stabilities.
