&lt;p&gt;我在使用SmartRF Studio对测试板1进行测试。测试板1的发射性能（868MHz）与其余测试板相同，RX性能（868MHz）低于其余测试板2~5db。&lt;/p&gt;
&lt;p&gt;备注：其余测试板包括LAUNCHXL-CC1310和旧版本的自制测试板，其中的CC1310均为REV B。测试板1为最新自制测试板，误装了REV A 的CC1310。所有自制测试板均按照TI最新参考设计进行设计，且省略了外部LF 晶振。&lt;/p&gt;
&lt;p&gt;我的问题：&lt;/p&gt;
&lt;p&gt;1.CC1310的版本问题（REV A），是导致TX性能正常，RX性能异常的原因吗？&lt;/p&gt;
&lt;p&gt;2.TI何时在中国进行了REV A至REV B的迭代？我在2026年购买的CC1310为REV A版本，是供应商的库存料还是fake芯片？&lt;/p&gt;
&lt;p&gt;谢谢。&lt;/p&gt;</description></item><item><title>CC1310: CC1310低频晶振在系统中的作用</title><link>https://e2echina.ti.com/thread/1074460?ContentTypeID=0</link><pubDate>Wed, 20 May 2026 09:26:23 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:29d030c5-8206-4d64-87e2-e61720ab52e9</guid><dc:creator>ancient frog</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1074460?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/wireless-connectivity/sub-1-ghz/f/sub-1-ghz-forum/1074460/cc1310-cc1310/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; CC1310&lt;/p&gt;&lt;p&gt;你好，&lt;/p&gt;
&lt;p&gt;我的测试板误装了REV A 的CC1310，同时没有放置外部低频晶振，所以我想咨询下，外部低频晶振（32.768kHz）主要会影响系统的哪一部分？换言之就是他会为系统的哪部分提供时钟？这些部分的功能是什么？（e.g.休眠定时？or射频定时器？）&lt;/p&gt;

&lt;p&gt;LNA有几个放大级，因此ESD击穿可能会损坏特定的RF灵敏度区域，但不会完全损坏无线电。事实可能并非如此，但这可能是一种解释。&lt;/p&gt;
&lt;p&gt;出于可重复性的原因，应以传导方式测量RSSI。当您在600米距离进行测量时，LNA将处于最大值，您对#1和#2芯片的RSSI测量在这里显示了良好的性能。如果你在-30 dBm RSSI距离范围内测量这些单位，那么即使数据可能没有任何损失，我也希望看到RSSI的差异。&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>CC1101: CC1101的RSSI读取数值异常</title><link>https://e2echina.ti.com/thread/1066350?ContentTypeID=0</link><pubDate>Thu, 02 Apr 2026 10:17:54 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:4374516a-2ff4-4f9d-a052-70e4f7b8342a</guid><dc:creator>Lott Yu</dc:creator><slash:comments>4</slash:comments><comments>https://e2echina.ti.com/thread/1066350?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/wireless-connectivity/sub-1-ghz/f/sub-1-ghz-forum/1066350/cc1101-cc1101-rssi/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; CC1101&lt;/p&gt;
&lt;p&gt;测试了5个CC1101模块，其中2个存在RSSI读取异常；433MH的频率，在1.2k空速，5.2K频偏、58k带宽下进行GFSK调制通信测试，使用信号源进行CC1101的接收数据包的RSSI数据读取测试和灵敏度测试。&lt;/p&gt;
&lt;p&gt;测试结果现出异常模块的RSSI接收数据包RSSI读取始终偏差较大且灵敏度也较差。同时使用另一个模块在固定位置进行发送，在同一块测试底板上，固定位置固定天线实际测试模块间的通信，异常模块的RSSI数据仍表现异常。&lt;/p&gt;
&lt;p&gt;将正常模块和异常模块的CC1101芯片进行交换，异常模块恢复正常，而正常模块出现RSSI异常的问题，可以看出异常跟随CC1101芯片变动，和模块的PCB以及外围器件无关。请问这是什么原因导致的异常。表格是记录的测试数据，其中1号和2号模块是异常模块，2、4和5号模块为正常模块，原始值是从CC1101的接收数据包中获取的RSSI，计算值是根据CC1101手册提供的计算方式得出的数据。&lt;/p&gt;
&lt;p&gt;疑问：&lt;/p&gt;
&lt;p&gt;1、是否CC1101芯片生产工艺有变化，导致数据包RSSI读取变动，有批次差异？&lt;/p&gt;
&lt;p&gt;2、是否有其它异常导致该问题？&lt;/p&gt;
&lt;p&gt;3、综上是否有解决方案&lt;/p&gt;
