The Connor-Winfield

ASOF5S3E is a 5V Surface

Mount Oven Controlled

Crystal Oscillator (OCXO)

with an HCMOS output. The

ASOF5S3E is designed for

Stratum 3E applications

requiring low jitter and tight

frequency stability.

Notes:

1) Labels will include the calibration frequency at the time of ship.

2) Initial calibration @ 25

°C

3) Overall Frequency Stability, 0° to 70°C

4) After ten days of continuous operation.

5) Allen Variance: 1 second, 100 average.

6) Frequency vs. change in supply voltage.

7) Frequency vs. change in load.

8) Vcc = 5.0Vdc.

9) From Vcc=90% of final value. No more than 16 transitions at start -up before oscillator

has started.

10) Measured @ 0

°C, within 5 minutes, referenced one hour after turn-on.

11) At time of delivery.

12) HCMOS load.

13) For a given off time, the time required to meet daily aging, short-term stability and TDEV

requirements.
