新型VCOCXO设计

Design of a Novel VCOCXO

叙述了一种新型的压控恒温晶体振荡器(VCOCXO)的设计方案。在恒温晶体振荡器(OCXO)研究的基础上,通过对芯片的挑选,电路的设计和改进后,研制成温度稳定度小于±5×10-8,频率稳定度达1-0 8数量级,电源电压为+12 V,外形尺寸为35.8 mm×25.7 mm×15 mm的小型高稳晶体振荡器。高度的集成度使电路简化,降低了功耗,提高了器件的可靠性。

The aim of this paper was to develop a novel voltage controlled oven-controlled crystal oscillator （VCOCXO） based on the design of the oven- controlled crystal oscillator （OCXO）. Through the choices of the chip and the design of the circuit, we developed a relatively simple high stability small size VCOCXO, whose power supply voltage is ＋12 V. The high integration simplified the circuit, and improved its reliability and stability.
