High Stability OH320 Series
Oven Stabilized Oscillator
OCXO / VCOCXO
Description
Connor-Winfield’s high stability OH320 series
are exceptionally precise frequency standards,
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 OH320 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 for temperature ranges 0 to 70°C and -20 to 70°C.
2. Frequency vs change in temperature, calculated as [(Fmax-Fmin)/(2*Fo)]. Control voltage at nominal value.
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 to the nominal control voltage.
Without any bias on the CV input, the VCOCXO frequency will be offset by approximately -1ppm.

RoHS compliant, lead free. See solder profile on page 6.
Refer to recommended reflow pre-heat and reflow temperatures on page 6. Package material
consists of hermetic seal 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 hermetic. 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!
