The Connor-Winfield
OVA3BA2AA is a true Surface
Mount 3.3V Voltage Controlled
Oven Stabilized Crystal
Oscillator (VCOCXO) with a
LVCMOS logic output. The
OVA3BA2AA is designed for
STRATUM 3 applications
requiring tight frequency stability,
low jitter over the industrial
temperature range.

Notes:
1) Initial calibration @ 25°C, Vc = 1.48 Vdc.
2) Frequency vs. temperature stabilit y referenced to 25°C.
3) Inclusive of calibration, operating t emperature range, supply voltage c hange, 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 m inutes of continuous operation at a st able 25°C.
6) Referenced to Fo @ 25°C, Positive Transfer Characteristic.
