大多数设计师都很熟悉通过穿孔门的拓扑结构,但很少有人真正明白如何做到这一点它能工作,更不用说如何工作了正确地设计。作为一个普通练习,大多数甚至不用付钱过多地注意普通有源振荡器在其设计上直到它不能正常工作,通常已经释放到生产。这是不应该的。许多系统或项目被推迟他们的部署是因为25分水晶没有按预期工作。振荡器应接收适当的数量在设计阶段的注意力在制造阶段之前。然后设计师就可以避开这个噩梦产品被退回的场景这个领域。CRYSTEK推出非常低的抖动的SMD时钟振荡器C3290-12.000,主要用于数字视频

我们将分析穿孔门振荡函数通过分解来实现它的组件。(一个更严格分析超出了本文的范围。)然而,简单的分析就足够了传达《穿山甲》的要点有源晶体振荡器的操作。此外,我们将提出一个简单的设计问题来教如何在Pierce-gate初始值处导出。

我们可以用巴克豪森准则来解释穿透门拓扑是如何工作的。该标准规定如下:周围收益的乘积循环必须等于或大于一个在期望的振荡频率。环上的相移必须为0或2π的任意整数倍(360°)。

2显示了相移分析Pierce-gate。如果U1为-180°相移,另加-180°的外部组件需要满足巴克豪森准则。的相移会自动调整到精确吗360°循环,以保持振荡。Crystek晶振公司技术人员分析出如果U1提供-185°相移,其余的组件将自动提供-175°相移在适当的反馈电阻Rf用于线性化数字CMOS逆变器。射频完成这一壮举是通过充电逆变器的输入电容,包括C1从输出逆变器。换句话说,就是反馈电阻将逻辑门转换为模拟放大器。很简单的巧妙的技巧添加一个电阻。

反馈电阻一般包括在微集成电路或专用集成电路中。使用以下程序来确定是否反馈电阻器集成在IC中:不连接外部组件

(C1, C2, X1),测量电压在逆变器的输入和输出处。如果反馈电阻在内部,那么输入端和输出端的电压将在Vcc/2左右。
如果反馈电阻不在里面,然后逆变器就会被锁住输入和输出都是a逻辑“1”或逻辑“0”或反之亦然。CRYSTEK推出非常低的抖动的SMD时钟振荡器C3290-12.000,主要用于数字视频
