随着设备使用时间的推移，进口有源晶振电压将以不同的速率下降，这取决于电池技术。处理器执行的操作也会对电源电压产生影响，因为有些操作会比其他操作消耗更多的电流。

高品质的时钟晶体振荡器ASV-24.000MHZ-E-T得到PC主板应用的喜爱，随着这一挑战在行业中越来越普遍，Abracon推出了连续电压振荡器，进口晶体振荡器产品线来解决这一挑战。表1概述了当前Abracon MHz系列产品。

连续电压振荡器中的CMOS集成电路有一个电压调节器，不仅隔离了偏置电压依赖性，而且显著减少了电流消耗和晶体驱动。这确保了在不同的源条件下更稳定的运行。

attery-dependent electronics have the challenge of dealing with a variable voltage source. The graph in Fig. 1 illustrates how the voltage of batteries diminishes under a constant current draw and how a fluctuating current draw can affect the supply voltage [1]. As the device is used over time, the voltage will slope downward at various rates, depending on the battery technology. The operations that the processor carries out will also have an impact on the supply voltage as some operations draw more current than others. With this challenge becoming more prevalent in the industry, Abracon has introduced a Continuous Voltage oscillator product line to address the challenge. Table 1 overviews the current Abracon MHz series offerings. The CMOS integrated circuits within the Continuous Voltage oscillators have a voltage regulator that not only isolates the bias voltage dependency but also significantly reduces current consumption and crystal drive.This ensures a much more stable operation under varying source conditions.
