&lt;p&gt;&amp;nbsp; &amp;nbsp; Currently, the overall system signal link is shown in the diagram. The sensor transmits data back to the FPGA at 16 Gbps via the DS160PR410. The FPGA uses Xilinx digital eye diagram IP core for testing. The current test results show that when the value is set to different values, the processing results of the digital eye diagram exhibit inconsistent passband flatness between the left and right half-regions. What could be the possible causes?&lt;/p&gt;

Number:&lt;/b&gt; DP83TC812-SCHEMATIC-REVIEW-CHECKLIST&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Test phenomenon: GD32F427 chip and 83848PHY chip. Normally, communication tests work fine, but after EMC testing (common mode 1000V, direct coupling), it causes communication to fail to establish a connection. A soft reset was performed on the GD32, during which the peripherals are re-initialized, and the PHY chip is also reset (pulling the reset pin low for 100us, while the manual requires 1us, plus a soft reset). After the GD software reset, the connection still cannot be established. However, after completely power cycling the machine, communication can be re-established.&lt;/p&gt;
&lt;p&gt;Question 1: Is this normal?&lt;br&gt;Question 2: What causes this, and how can software handle it?&lt;br&gt;Question 3: Is there a difference between pulling the hardware reset pin low to reset and power cycling?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>DP83848K: 通信异常</title><link>https://e2echina.ti.com/thread/1094075?ContentTypeID=0</link><pubDate>Fri, 11 Sep 2026 03:42:05 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:dc45edfb-a1e9-4668-a806-302842370cee</guid><dc:creator>Fiona Tan</dc:creator><slash:comments>3</slash:comments><comments>https://e2echina.ti.com/thread/1094075?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/interface/f/interface-forum/1094075/dp83848k/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/DP83848K" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;DP83848K&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;测试现象：GD32F427 芯片 + 83848PHY 芯片，平时通信测试功能正常，但是打 EMC（共模 1000V，直接耦合）测试后，导致通信无法建立连接，对 GD32 进行了软复位，复位的过程中会重新初始化外设，也会对 PHY 芯片进行复位（拉低复位引脚 100us，手册要求是 1us，还有软复位），GD软件复位后还是无法建立连接。但是整个机器重新断电重启后，可以建立通信连接。&lt;br&gt;问题1：这个是不是正常现象？&lt;br&gt;问题2：这是什么原因导致的，软件怎么处理？&lt;br&gt;问题3：拉低硬件复位引脚进行复位，和断电复位有什么区别吗？&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>TCA9555: Do we have a version of the TCA9555 without the clamp diode?</title><link>https://e2echina.ti.com/thread/1094068?ContentTypeID=0</link><pubDate>Fri, 11 Sep 2026 02:58:33 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:67a4f94d-c4f3-4b6d-a7ca-22333d1900b1</guid><dc:creator>Chance Zhan</dc:creator><slash:comments>1</slash:comments><comments>https://e2echina.ti.com/thread/1094068?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/interface/f/interface-forum/1094068/tca9555-do-we-have-a-version-of-the-tca9555-without-the-clamp-diode/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/TCA9555" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TCA9555&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;The customer wants a version of the TCA9555 without input clamp diodes.

&lt;p&gt;请问一下DP83822H在时序要求中描述，T3的经典值是120ns，那么请问reset pin如果加了比较大的滤波RC，比如1Kohm/10nF，那么波形会变得非常缓慢。&lt;/p&gt;
&lt;p&gt;如果按照50%电压测试，则有可能观察到Strap pin先恢复，Reset才到50%电压值，T3变为负值&lt;/p&gt;
&lt;p&gt;请问Reset pin的推荐滤波参数是多少？如果Strap pin不额外增加外部滤波电容，在Power-on或者reset结束释放时，上升下降时间是多少？&lt;/p&gt;

The questions are: &lt;br&gt;(1) How can communication anomalies (such as connection loss) with the DP83848 be detected by microcontroller? &lt;br&gt;(2) How can the microcontroller restore communication via software after a DP83848 communication anomaly occurs, without power-cycling the device?&lt;br&gt;(3) What hardware measures can be implemented to enhance interference immunity?&lt;br&gt;    thanks!&lt;/pre&gt;

&lt;p&gt;Hi Ti Team,&lt;/p&gt;
&lt;p&gt;我们设备采用的MIPI-&amp;gt;LVDS方案，选的SN65DSI83芯片。&lt;/p&gt;
&lt;p&gt;目前现象：&lt;/p&gt;
&lt;p&gt;偶发上电屏幕横向周期性闪烁（横向撕扯的现象，横线撕扯马上又恢复正常，然后0.5s~1s立马又出现横向撕扯，如此周期性重复）。而且一旦上电出现闪烁，会一直存在，不会自动消失。如果上电没有出现闪烁，后续不会出现闪烁。&lt;/p&gt;
&lt;p&gt;屏幕参数：&lt;/p&gt;
&lt;p&gt;clock frequency: 74284800Hz&lt;/p&gt;
&lt;p&gt;H-Active: 1280&lt;/p&gt;
&lt;p&gt;V-Active: 800&lt;/p&gt;
&lt;p&gt;H-back porch: 88&lt;/p&gt;
&lt;p&gt;H-front porch: 72&lt;/p&gt;
&lt;p&gt;H-sync-len: 20&lt;/p&gt;
&lt;p&gt;V-back porch: 23&lt;/p&gt;
&lt;p&gt;V-front porch: 15&lt;/p&gt;
&lt;p&gt;V-sync len: 10&lt;/p&gt;
&lt;p&gt;试过改动过back porch/front porch/sync len/clock frequency,都无法解决。&lt;/p&gt;
&lt;p&gt;做过的测试：&lt;/p&gt;
&lt;p&gt;1.在横向闪烁的时候，通过IIC切换SN65DSI83到测试模式，屏幕没有出现闪烁，再切回正常模式，又恢复横向闪烁；&lt;/p&gt;
&lt;p&gt;2.在横向闪烁的时候，通过IIC设置PLL_EN到disable再到enable，屏幕黑屏后会恢复到正常显示界面（没有闪烁）；如果多次切换PLL_EN disable/enable，会偶发出现屏幕闪烁现象。&lt;/p&gt;
&lt;p&gt;3.在横向闪烁的时候，通过IIC设置CHA_SYNC_DELAY,设置奇数的时候，屏幕不闪烁，设置偶数的时候屏幕出现横向闪烁。&lt;/p&gt;
&lt;p&gt;重新上电复现横向&lt;span&gt;闪烁&lt;/span&gt;，通过IIC设置CHA_SYNC_DELAY,设置偶数的时候，屏幕不闪烁；设置奇数的时候，屏幕出现横向闪烁。&lt;/p&gt;
&lt;p&gt;4.再横向闪烁的时候，带电重新插拔LVDS排线，存在50%的概率屏幕恢复正常（不闪烁）。&lt;/p&gt;
&lt;p&gt;5.更改LVDS屏幕的各种设置以及复位时间，VGH/VGL时序，均不能解决闪烁现象。而且在出现上电横向闪烁的时候，屏幕自带的VGH和VGL均出现周期性跌落现象，VGH（VGH=18V）的跌落幅度在5~7V左右，VGL（VGL=-10V）的跌落幅度在3~5V左右。&lt;/p&gt;
&lt;p&gt;请问一下，出现这种横向闪烁，需要怎么排查解决？&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: TUSB522P: TUSB522P-短线丢帧问题</title><link>https://e2echina.ti.com/thread/1091898?ContentTypeID=0</link><pubDate>Fri, 28 Aug 2026 01:17:26 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:a8780812-d132-41a3-9a88-07689d0d8980</guid><dc:creator>Wu Xu</dc:creator><slash:comments>3</slash:comments><comments>https://e2echina.ti.com/thread/1091898?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/interface/f/interface-forum/1091898/re-tusb522p-tusb522p-/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Other Parts Discussed in Thread: &lt;/b&gt;&lt;a href="https://www.ti.com.cn/product/cn/TUSB1104" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TUSB1104&lt;/a&gt;&lt;/p&gt;&lt;p&gt;好的，谢谢。&lt;/p&gt;
&lt;p&gt;此外，想问一下，如果我们改版想换成自适应调节增益的，有型号推荐吗？&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>AM26C31: AM26C31丝印信息</title><link>https://e2echina.ti.com/thread/1091401?ContentTypeID=0</link><pubDate>Wed, 26 Aug 2026 01:46:16 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:8ff95f7c-7327-4e96-89c9-3f497b613368</guid><dc:creator>PANPAN  NAN</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1091401?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/interface/f/interface-forum/1091401/am26c31-am26c31/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt;
