Thru-Hole VCXOs, 3.3V
Thru-hole 3.3V VCXOs are available for the first
time, and in a variety of off-the-shelf models.
Versions in full size (M) and half size (H) cans
are offered as standard designs for 0 to 70°C.
These models are recommended for new
equipment designs that operate at 3.3V to
minimize current, power, and heat dissipation.
Many combinations of pull, control voltage and
center frequency deviation are available, to
accommodate a wide variety of filtering and
driving circuitry. For additional input voltage/
deviations and operation through 175 MHz see
our 5V models. For operation from -40 to
+85°C see our temperature extended models.

Thru-Hole / Gull Wing, 3.3V
1 MHz to 125 MHz
These 3.3V VCXOs generate an HCMOS frequency
output which is controlled by an input voltage.
The end-point frequency/voltage parameters are
defined, as is the center frequency.
CAPTURE RANGE
The Frequency-Capture range is equal to the (Center-Frequency ± the
Frequency Deviation), because every MF VCXO is ATE-tested to meet the
Frequency-Deviation over the temperature range.
Frequency Capture
specification includes all effects of temperature and supply voltage.
It is not necessary to make additional capture allowances.

FREQUENCY STABILITY
Frequency stability vs. Temperature (0 to 70°C) is typically better than
±20 ppm. Since the deviation of each oscillator is tested and guaranteed
over the whole operating temperature range, it is not necessary to make
additional capture allowances. All oscillators will capture frequencies with
the full minimum values of the deviation under all conditions.
QUALITY
Each VCXO is computer-tested at three temperatures to guarantee
full compliance to the specification.
