CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

ASOF3S3P is a surface

mount, 3.3V Oven Controlled

Crystal Oscillator (OCXO)

with a HCMOS / TTL

compatible output. The

ASOF3S3P is designed for

higher frequency stability

Stratum 3 Plus applications

requiring low jitter and tight

frequency calibration.

Notes:

1) Initial calibration @ 25

°C at time of shipment.

2) Frequency vs. temperature stability, 0 to 70°C absolute.

3) Frequency stability per 5% change in supply voltage.

4) Frequency stability per 5% change in load

5) Inclusive of calibration, operating temperature range, supply voltage change, load change, shock

and vibration and aging over 20 years.

6) Measured @ 25

°C, within 5 minutes, the unit will be within +/-0.5ppm of nominal.

7) 24 hours off then 60 minutes on at a constant temperature and voltage.

8) Supply voltage at 3.3 Vdc.
