CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
ESOF3S3 is a true Surface
Mount 3.3V Oven Controlled
Crystal Oscillator (OCXO)
with an HCMOS output. The
ESOF3S3 is designed for
Stratum 3 applications
requiring tight frequency
stability and low jitter.

Notes:
1) Initial calibration @ 25
C
2) Frequency vs. temperature stability
3) Inclusive of calibration, operating temperature range, supply voltage change, shock and vibration
and aging (20 years).
4) Specifications at time of shipment after 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 25
C.
