CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
ASOF3S3 is a true Surface
Mount 3.3V Oven Controlled
Crystal Oscillator (OCXO)
with an LVCMOS output. The
ASOF3S3 is designed for
Stratum 3 applications
requiring tight frequency
stability and low jitter.

grounded metal cover.
PROCESS RECOMMENDATIONS
TABLE 5.0
Soldering Process
See the solder profile on page 2.
Wash
Ultrasonic cleaning is not recommended

Notes:
1) Initial calibration @ 25C
2) Frequency vs. temperature stability
3) Inclusive of calibration, operating temperature range, suppl y voltage change, shock and
vibration and aging (20 years).
4) Specifications at time of shipm ent after 48 hours of operation.
5) Measured @ 25C, within 5 minutes, the unit will be within +/-0.1ppm of its reference
frequency, measured after 30 minutes of continuous operation at a stable 25C.
