Oven Controlled Crystal Oscillators (OCXO’s)
EX-240 (EMXO)
Description:
The EX-240 Series offers a ruggedized hybrid thick film construction in a low
profile, hermetically sealed 16 pin DDIL package, which can withstand severe
environmental conditions. This product series utilizes VI’s EMXOTM technology
resulting in excellent stability performance and fast warm-up with low power
consumption.
Features:
* Temperature Stability: to ±1 x 10-8 over 0°C to +50°C
* Acceleration Sensitivity: < 1 x 10-9 / g Total Gamma
* Low power consumption: < 0.7 W @ +25°C
* Shock: 1,000g’s peak, 0.5 ms
* Vibration: 20g peak to 2 kHz (Sine), 30 Grms overall to 2 kHz (Random)
