NOTE
The Connor-Winfield
OFA3BB2AA is a true Surface
Mount 3.3V Oven Controlled
Crystal Oscillator (OCXO) with
an LVCMOS logic output. The
OFA3BBA2AA is designed for
STRATUM 3 applications
requiring tight frequency
stability, low jitter over the
industrial temperature range.

ENVIRONMENTAL CHARACTERISTICS
Temperature Cycle: Per MIL-STD-883, Method 1010, Condition B. -55°C to 125°C, 300 cycles, 10 minute dwell, 1 minute
transition.
MECH ANICAL CHAR ACTERI STICS
Vibration: Per MIL-STD-202, Method 204, Condition A. 10G’s peak, 10Hz to 500Hz, 15 minute cycles, 12 times each
perpendicular axis.
Shock: Per MIL-STD-202, Method 213, Condition F. 1500G’s, 1.0ms, half sine, 3 shocks per direction.
Moisture Resistance: Per MIL-STD-202, Method 106. 95% RH @ 65°C, 10 cycles 10°C to 65°C.
Notes:
1) Initial calibration @ 25°C.
2) Frequency vs. temperature stability overall, -40 to 85°C.
3) Inclusive of calibration, operating tem perature range, supply voltage change, shock and
vibration and aging (10 years).
4) Specifications at time of shipment af ter 48 hours of operation.
5) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference
frequency, measured after 30 minutes of continuous operation at a stable 2 5°C.
