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.

HY is predetermined, HX is for "1 ppm Forever" max temp range -20 to +70
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.
