• RE: My PLL is occasionally losing lock.  Why?

    There are a variety of causes of why a PLL will occasionally lose lock.

    This answer assumes that the user is able to make their PLL lock, but it doens't stay locked.

    The most common causes are:

    1. Poor power and/or signal connections. Be sure that…

  • ADI针对电子测试和测量的RF和微波解决方案,优势在哪?

    RF和微波IC广泛用于电子测试和测量仪器,比如频谱分析仪、网络分析仪、信号发生器和通信测试仪。当无线通信在我们的生活中变得越来越普及,比如4G/5G和物联网,对于它们的测试基准的要求也在不断提高。在ADI针对电子测试和测量的RF和微波解决方案中,重点讨论ADI产品如何融入相关信号链。

    主要挑战和系统设计考虑


    宽动态范围

    最小化RF测试台的噪底(比如相位噪声)对于保持宽动态范围内的测试信号纯度很重要。但是,更多的数字信号处理任务将增加辐射噪声,因此获得干净的信号是个难题。

  • Baking the AD9951A

    Does this part have to be baked 24hours prior soldering it.

     

    Only packages which exceed the recommended storage conditions should be baked
    before reflow soldering. The AD9951 has a Moisture Sensitivity Level rating of

  • Want to use AD9510/11's DLD as our lock alarm, but it may not work properly if the reference disappears. Any solution?

    We want to use the DLD as our lock alarm, but the datasheet  suggests it might
    not work properly if the reference  disappears.
     
    The PLL does not automatically recover if you enable the "loss  of reference"
    detection circuit that…
