Description
Connor-Winfield’s high stability OH300 series
are exceptionally precise frequency standard,
excellent for use in cellular base stations, test
equipment, Synchronous Ethernet, VSAT and
STRATUM 3E applications
These unique OCXO / VCOCXO
Oscillators 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
Voltage Controlled option.
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.

Notes:
1. ±5.0 ppb stability models are only available from 0 to 70°C.
2. Referenced to the frequency measured @ 25°C. OCXO with EFT, the 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 VCOCXO, the control voltage input must be biased the nominal control voltage.
Failure to bias the Vc input will cause an unstable output condition.

RoHS compliant, lead free. See solder profile on page 6.
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!
