锁相环常见问题解答（15问）

🔷什么是PLL频率合成器?

利用频率合成器，设计人员可以产生单一参考频率的各种不同倍数的输出频率。其主要应用是为RF信号的上变频和下变频产生本振(LO)信号。频率合成器在锁相环(PLL)中工作，其中鉴频鉴相器(PFD)将反馈频率与基准频率的某一分频形式相比较(图1)。PFD的输出电流脉冲经过滤波和积分，产生一个电压。此电压驱动一个外部电压控制振荡器(VCO)提高或降低输出频率，从而驱动PFD的平均输出接近零。

使用多个时钟时，如何改善系统性能？
在使用同一时钟源产生多个时钟时，一个常见的问题是噪声，通常表现为存在于噪底之上的杂散，这是因为单一时钟源被倍频或分频为多个时钟。偏移各时钟的相邻沿可以降低噪声杂散，或者完全消除杂散，这具体取决于系统的时序裕量。这一现象是一个时间变量系统，其中时钟信号的破坏与时域中的干扰位置相关。干扰位置是固定的，因此时钟的破坏程度与干扰的幅度成比例，就像在线性系统中一样。

确定杂散来源是DDS/DAC还是其他器件
直接数据频率合成器(DDS)因能产生频率捷变且残留相位噪声性能卓越而著称。另外，多数用户都很清楚DDS输出频谱中存在的杂散噪声，比如相位截断杂散以及与相位-幅度转换过程相关的杂散等。此类杂散是实际DDS设计中的有限相位和幅度分辨率造成的结果。其他杂散源与集成DAC相关——DAC的采样输出产生基波和相关谐波的镜像频率。另外，因DAC非理想的开关属性可能导致低阶谐波的功率水平升高。最后一种杂散源是在系统时钟频率的基波与任何内部分谐波时钟(例如，ADI直接数字频率合成器提供的SYNC_CLK)之间产生的混频产物。
如果通过改变DDS频率调谐字使杂散与DDS/DAC相关，则并不难确定杂散源。这是因为改变调谐字时，上述所有杂散噪声的频率偏移均随基波变化。
图1所示为DDS的500MHz参考时钟，由一个100KHz音实现10%的AM调制。该参考时钟源是一款Rohde andSchwartz具有调制功能的SMA信号发生器。图1中的灰色线为无调制条件下的参考时钟。图2中，同一100KHz音以完全相同的频率偏移传输到DDS/DAC输出，不受调谐字频率影响。图2中的频率调谐字表现出四个相互叠加的不同DDS载波。注意，在全部四个载波改变时，参考时钟杂散的频率偏移保持不变；但该杂散的幅度以20log(x)为单位发生变化，其中，x为参考时钟频率与DDS载波频率之比。

超范围事件中，ADC的输出数据会是什么样
偶尔会有人问，常常是年龄较大的工程师问：在超范围情况发生时，转换器的输出数据是什么？第一次听到这个问题（许多年前）时，我觉得有点可笑。但是，一位更有经验的同事解释说，早期集成ADC通常会表现出一种称为“翻转”的行为。
多数现代高速ADC都有一个超范围(OR)标志。该输出位通常与转换器的输出数据同步，表示模拟输入样本超过了转换器的满量程输入范围。考虑一个使用偏移二进制编码的ADC。如果输入信号超过转换器的正满量程范围，ADC将钳位，输出数据将为全1（12位ADC是111111111111）。如果输入超过其负满量程范围，输出将为全0（12位ADC是000000000000）。两种情况下，OR位都会置1，表示在该采样期间输入超出范围。
相比之下，对于具有翻转行为的旧式12位转换器，如果其输入为正满量程+1LSB，则其输出可能是000000000001，而不是全1。用户可从OR输出得知ADC已超范围，该数据应当被忽略。对于一款具有两倍输入范围的13位转换器，这些位原本是正确的低12位，但对于一款12位转换器，该输出表示输入比负满量程高1LSB。可以想象，这在任何系统中都可能引起问题。
但是，使用ADI公司的高速转换器时请放心，您不必担心此类问题。我从1980年代开始就与这些产品打交道，所有这些年来，我们从未发布一款包含这个问题的产品。很可能是早先时候，有几位工程师被这个问题坑过，所以认真仔细地予以解决，确保它不再坑人。
