FAQ
Q1: What are the advantages of Suzhou Hangjing's oven-controlled crystal oscillators (OCXOs) OD25S5 series?
A: 1)Extremely low phase noise and jitter
2)Strong resistance to harsh environmental conditions
3)Outstanding Long-Term Aging Rate
Q2: Why is the power consumption of OCXOs so high? How can it be reduced?
A: High Power Consumption Cause: Power is primarily consumed by the internal heater. Maintaining the crystal at high temperatures (e.g., 70–85°C) in low ambient temperatures (e.g., -40°C) requires significant energy, especially during the start-up (warm-up) phase when power peaks (typically several watts).
Q3: Suzhou Hangjing's Extended Temperature Sine Wave OCXOs 25 x 25 series PACKAGING INFORMATION
A: 1)Packaging in antistatic foam tray
2)QTY per tray: 20pcs
