STRATUM 3E High Stability
Oven Stabilized Oscillator
OH300 Series
OCXO – OCVCXO
Description
Connor-Winfield’s high stability OH300
OCXO / OCVCO series are exceptionally
precise frequency standard, excellent for
use in cellular base stations, test equipment,
Synchronous Ethernet, VSAT and Stratum 3E
applications
These unique OCXOs and OCVCXOs
provide frequency stabilities in the range of
±10
ppb to
±50
ppb, over the commercial,
extended commercial or the industrial
temperature range. Power requirements are
1.1W over the commercial temperature range
and 1.5W over the industrial temperature
range after warm-up. Additionally, excellent
aging is achieved through the use of
overtone SC cut crystals.
The OH300 series is available with
CMOS logic or Sinewave output along
with Electronic Frequency Tuning. These
oscillators provide outstanding phase
noise that varies depending on frequency
requirements. Allan Variance specifications
are rated for primary reference standards.
Warm up times are on the order of 5 minutes
to 0.10 ppm of final frequency.

2. At time of shipment after 48 hours of operation.
3. Inclusive of calibration, operating temperature, supply voltage change, load change and 20 years aging.
4. Minimum "Power On Time" after rail rises from 0 to within +/-5% of Vcc = 1 second.
Vcc ramp rate must be <0.3 volts per millisecond.
5. Measured with Vcc = Nominal, in calm air.
6. Measured @ 25°C, within ±100 ppb, referenced one hour after turn-on.
7. To ensure proper operation of OCVCXO's the control voltage input must be biased the nominal control voltage. Failure
to bias the Vc input will cause an unstable output condition.
