&lt;p&gt;1、我想知道这会不会与我们使用100MHz，而评估板使用的是125MHz晶振有关。&lt;/p&gt;
&lt;p&gt;2、由于ADI官方提供的评估板BOM表中，125MHz晶振已经没有这个型号，只能更换型号或使用同一型号其他频率。有什么建议吗&lt;/p&gt;
&lt;p&gt;3、如果使用其他频率，会不会对输出信号质量有影响呢，我使用ADIsimPLL仿真，感觉两种频率的输出也没啥区别。是否需要更换外部环路滤波器设计呢，应该怎么设计呢&lt;/p&gt;

&lt;p&gt;我正在使用 EVAL-AD7134FMCZ 评估板和 SDP-H1 控制板进行数据采集。该系统此前可以正常识别并完成数据采集，但在完成一组采集后突然无法继续工作。&lt;/p&gt;
&lt;p&gt;目前的现象如下：&lt;/p&gt;
&lt;p&gt;1. SDP-H1 和 AD7134 评估板均已正常供电，板上指示灯亮起，SDP-H1 通过外接圆形 DC 电源接口供电。&lt;br /&gt;2. Windows 设备管理器能够正常识别 &amp;ldquo;Analog Devices SDP-H1&amp;rdquo;。&lt;br /&gt;3. 如果先打开评估软件，再连接 USB，Hardware Select 窗口能够识别到 &amp;ldquo;SDPH1: AD7134&amp;rdquo;，并提示对应板卡的 LED1 闪烁。&lt;br /&gt;4. 但是选中该板卡后，软件立即提示 &amp;ldquo;Power up check failed!&amp;rdquo;。&lt;img style="max-height:240px;max-width:320px;" src="https://ez.analog.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/1162/1537.IMG_5F00_2403.jpeg" alt=" " /&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://ez.analog.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/1162/2768.png" alt=" " /&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://ez.analog.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/1162/30325.png" alt=" " /&gt;&lt;/p&gt;

&lt;p&gt;我们购买了LTC3884芯片的演示板（DC2165A，LTC3884EUK演示板双通道PMBus降压转换器，4.5V &amp;le; VIN &amp;le; 14V, VOUT0/VOUT1 = 0.5V 至 1.8V @ 30A），DC2165A演示板自带出厂时配置好的LTC3884芯片，在LTpowerPlay软件上的功能演示均正常。我们还购买了几颗独立的未经配置的LTC3884芯片。&lt;/p&gt;
&lt;p&gt;我们目前遇到的问题是，我们将DC2165A演示板上自带的LTC3884芯片拆下来，再装上购买的未经初始化配置的LTC3884芯片，LTpowerPlay软件显示（未将对象设置为实例），并且也无数据读出，我们猜测的原因是新换上的芯片未经初始化配置，所以想请教一下如何将新换上的芯片结合演示板和软件进行初始化配置。&lt;/p&gt;
&lt;p&gt;非常感谢并期待您的解答！&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>ADRV9009射频端口差分匹配</title><link>https://ez.analog.com/thread/605092?ContentTypeID=0</link><pubDate>Mon, 06 Jul 2026 09:41:56 GMT</pubDate><guid isPermaLink="false">a884d118-f55f-49de-87eb-b9dbaf99b3e3:1ada9d48-5ebb-44d2-bfd4-5537852822f1</guid><dc:creator>qdhd</dc:creator><slash:comments>1</slash:comments><comments>https://ez.analog.com/thread/605092?ContentTypeID=0</comments><wfw:commentRss>https://ez.analog.com/cn/other-products/f/forum/605092/adrv9009/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;如何利用ADS仿真软件仿真ADRV9009射频端口的阻抗匹配&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>AD215替代方案</title><link>https://ez.analog.com/thread/605090?ContentTypeID=0</link><pubDate>Mon, 06 Jul 2026 09:07:23 GMT</pubDate><guid isPermaLink="false">a884d118-f55f-49de-87eb-b9dbaf99b3e3:50eab850-4946-4492-8bd4-dc74d41855cb</guid><dc:creator>henan</dc:creator><slash:comments>1</slash:comments><comments>https://ez.analog.com/thread/605090?ContentTypeID=0</comments><wfw:commentRss>https://ez.analog.com/cn/other-products/f/forum/605090/ad215/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;AD215已经停产，要做电源隔离，有没有AD215的替代方案。&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>LTZ1000 噪声</title><link>https://ez.analog.com/thread/605073?ContentTypeID=0</link><pubDate>Fri, 03 Jul 2026 08:28:29 GMT</pubDate><guid isPermaLink="false">a884d118-f55f-49de-87eb-b9dbaf99b3e3:18c230fd-bb86-4576-8912-94b7f4cd6481</guid><dc:creator>cctang</dc:creator><slash:comments>1</slash:comments><comments>https://ez.analog.com/thread/605073?ContentTypeID=0</comments><wfw:commentRss>https://ez.analog.com/cn/other-products/f/forum/605073/ltz1000/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;问题描述：LTZ1000 数据手册查询到在10HZ到100HZ范围内，在齐纳管电流为4mA条件下，测试出齐纳管电压噪声应为50 nv/&amp;radic;HZ左右，但是我测试出的齐纳管输出电压噪在400&lt;span&gt;nv/&lt;/span&gt;&lt;span&gt;&amp;radic;HZ左右，相差接近一个数量级。请问下adi官方是如何去测试这个指标的？&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; 目前我正在学习ADSP-21593开发。我手里有&amp;ldquo;EV-SOMCRR-EZKIT REV D&amp;rdquo;底板和&amp;quot;EV-21593-SOM REV A&amp;quot;开发板，另外还有SOM 转接板&amp;ldquo;EV-SOMCRR-BRKOUT&amp;rdquo;。连接方式如下：&lt;br /&gt; &lt;img style="max-height:285px;max-width:228px;" src="https://ez.analog.com/resized-image/__size/456x570/__key/communityserver-discussions-components-files/1162/8562.pastedimage1781665473009v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;我遇到的问题是用cces IDE调试（Debug）时报&amp;ldquo;&lt;span style="color:#cc0000;"&gt;&lt;span class="text-only" data-eleid="3"&gt;&lt;b&gt;[TpsdkServer] Timeout waiting for processor to halt.&lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&amp;rdquo;&lt;/p&gt;
&lt;p&gt;操作步骤如下：&lt;/p&gt;
&lt;p&gt;1，打开cces IDE。（CCES版本时3.0.3）&lt;/p&gt;
&lt;p&gt;2，新建t2工程，如下：&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:419px;max-width:659px;" src="https://ez.analog.com/resized-image/__size/1318x838/__key/communityserver-discussions-components-files/1162/2117.pastedimage1781665473016v2.png" alt=" " /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;img style="max-height:421px;max-width:681px;" src="https://ez.analog.com/resized-image/__size/1362x842/__key/communityserver-discussions-components-files/1162/1638.pastedimage1781665473018v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;3，编译&lt;/p&gt;
&lt;p&gt;4，配置Debug Configuarations... 选择EZ-KIT Lite&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&amp;nbsp;&amp;nbsp; 默认生成的配置&lt;br /&gt; &lt;img style="max-height:507px;max-width:746px;" src="https://ez.analog.com/resized-image/__size/1492x1014/__key/communityserver-discussions-components-files/1162/3005.pastedimage1781665473020v4.png" alt=" " /&gt;&lt;img style="max-height:509px;max-width:767px;" src="https://ez.analog.com/resized-image/__size/1534x1018/__key/communityserver-discussions-components-files/1162/1447.pastedimage1781665473023v5.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;5，我将ADSP SOM的BMODE拨到了0位置（not boot）模式，连接电源与usb.&lt;/p&gt;
&lt;p&gt;6，点击CCES的Debug后出现如下问题：&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:497px;max-width:761px;" src="https://ez.analog.com/resized-image/__size/1522x994/__key/communityserver-discussions-components-files/1162/3348.pastedimage1781665473026v6.png" alt=" " /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;img style="max-height:496px;max-width:779px;" src="https://ez.analog.com/resized-image/__size/1558x992/__key/communityserver-discussions-components-files/1162/1067.pastedimage1781665473031v7.png" alt=" " /&gt;&lt;/p&gt;

&lt;td&gt;&lt;strong&gt;&lt;span class=""&gt;信号路径&lt;/span&gt;&lt;/strong&gt;&lt;/td&gt;

&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;两块板卡的 AD9988 使用了&lt;/span&gt;&lt;strong&gt;&lt;span class=""&gt;完全相同的 SPI 寄存器配置&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;。&lt;/span&gt;&lt;/p&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;strong&gt;&lt;span class=""&gt;关键差异：&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;ol start="1"&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;我们的信号路径中多了一个&lt;/span&gt;&lt;strong&gt;&lt;span class=""&gt;限幅器&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;（开发板没有）。&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;开发板在巴伦之后、进入 AD9988 之前，&lt;/span&gt;&lt;strong&gt;&lt;span class=""&gt;P 和 N 各串联了一个 0.1&amp;micro;F 电容&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;；我们的板卡在限幅器之后，P 和 N 是直接连接 AD9988，&lt;/span&gt;&lt;strong&gt;&lt;span class=""&gt;没有这两个电容&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;。&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;strong&gt;&lt;span class=""&gt;问题描述：&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;&lt;/span&gt;&lt;br /&gt;&lt;span class=""&gt;在相同输入信号条件和相同 AD9988 配置下：&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;strong&gt;&lt;span class=""&gt;开发板：&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;频谱干净，信号功率正常。&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;strong&gt;&lt;span class=""&gt;我们的定制板卡：&lt;/span&gt;&lt;/strong&gt;&lt;span class=""&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;杂散和谐波明显增多，目标信号功率明显偏低。&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;strong&gt;&lt;span class=""&gt;问题：&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;ol start="1"&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;开发板上巴伦输出端 P/N 各串联的 0.1&amp;micro;F 电容是否起关键作用？我们的板卡缺少这两个电容，会不会导致 ADC 内部共模偏置与限幅器输出冲突，从而产生失真？&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;限幅器本身是否可能是杂散和谐波的主要来源？信号幅度未达到限幅门限时，限幅器是否仍可能引入非线性失真？&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;在同时引入限幅器的情况下，是否需要在限幅器输出端也加上类似开发板的 P/N 串联电容？还是限幅器本身就与 AD9988 的交流耦合输入不兼容？&lt;/span&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;&lt;/span&gt;我们板卡的设计是否合理，有不合理的地方吗&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p class="ds-markdown-paragraph"&gt;&lt;span class=""&gt;这是我们的板卡硬件设计和信号采集情况&lt;/span&gt;&lt;/p&gt;

&lt;div id="dstWord1" class="result-item" data-v-54101870=""&gt;In this discussion, I learned that the maximum data length supported by the software for the AD9653 evaluation board is 65536. I have two questions:&lt;/div&gt;
&lt;div id="dstWord2" class="result-item" data-v-54101870=""&gt;1. Where can I obtain the HSC-ADC_EVALC FPGA configuration files?&lt;/div&gt;
&lt;div class="result-item" data-v-54101870=""&gt;2. If the DDR is configured, can VisualAnalog support the collection of more than 65536 data points?&lt;/div&gt;
