Description
Connor-Winfield’s high stability OH300
OCXO / OCVXCO 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
±5 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.

Absolute Ratings: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress
ratings only. The functional operation of the device at those or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to conditions outside the "recommended operating conditions" for any extended period of time may adversely
impact device reliability and result in failures not covered by warranty.

Notes:
1. ±5.0 ppb stability models are only available from 0 to 70°C.
2. Referenced to the frequency measured @ 25°C. OCVCXO control voltage (Vc) = nominal voltage.
3. At time of shipment after 48 hours of operation.
4. Inclusive of calibration, operating temperature, supply voltage change, load change and 20 years aging.
5. Supply voltage must reach Vcc levels monotonically within a ramp-up time of <12 ms.
6. Measured with Vcc = Nominal, in calm air.
7. Measured @ 25°C, within ±100 ppb, referenced one hour after turn-on.
8. 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.

Solder Process Recommendations: RoHS compliant, lead free. See solder profile on page 6.
In-line reflow: Refer to recommended reflow pre-heat and reflow temperatures on page 6. Package material
consist of Ryton R-4 high temperature cover with FR4 substrate. Component solder is Pb free high
temperature eutectic alloy with a melting point of 221°C.|
In-line oven profile: We recommend using KIC profiler or similar device placing one of the thermocouples on the
device to insure that the internal package temperature does not exceed 221°C.
Removal of device: If for any reason the device needs to be removed from the board, use a temperature controlled
repair station with profile monitoring capabilities. Following a monitored profile will insure the
device is properly pre-heated prior to relow. Refer to IPC 610E for inspection guidelines.
Recommended Cleaning Process: (If required)
Device is non-hermetic, water resistance with four weep holes, one in each corner to allow
moisture to be removed during the drying cycle. We recommend in-line warm water wash
with air knife and drying capabilities. If cleaner does not have drying capability, then use hot air
circulated oven. Boards should be placed in the oven vertically for good water runoff
Device must be dried properly prior to use!
Note: If saponifier is used make sure the device is rinsed properly to insure all residues are removed. PH of saponifier should
not exceed 10.
Drying Temperature: Between 85 to 100°C.
Drying Time: Time will vary depending on the board size.
Caution: Do not submerge the device!
