VCOCXO
The Connor-Winfield OX125 TiMax Series is a
5V Voltage Controlled Oven Controlled Crystal
Oscillator (VCOCXO) with an HCMOS output.
The OX125 Series is designed for Stratum 3E
applications requiring low jitter and tight
frequency stability.

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.
