VCXO-1 OSCILLATOR
500 kHz to 60 MHz*
Voltage Controlled Crystal Oscillator
™
DESCRIPTION
STATEK’s VCXO-1 consists of a TTL and CMOS
compatible hybrid circuit and a miniature AT-cut quartz
crystal (hermetically sealed in its own ceramic package)
together in a hermetically sealed metal DIP. This double
hermetic seal and the lack of trimming capacitors gives this
VCXO-1 exceptionally low aging. This VCXO-1 is well
suited for both frequency capture and frequency modulation
applications.
VCX0-40.0MHz
*Consult factory for other frequencies.

1. The maximum allowed frequency deviation at 25OC from reference frequency.
Minimum available tolerance is pullability dependent.
2. The maximum allowed frequency deviation from the frequency at 25OC. Minimum
available tolerance is dependent upon the Operating Temperature Range.

3. Maximum available pullability is frequency dependent, up to 200 ppm available.
4. With a total pull of 200 ppm, a linearity of 10% guarantees that there is a linear
frequency-voltage relationship such that the operating frequency will be within
(200 ppm) x (10%) = 20 ppm of this line over the entire control voltage range.
