Where should I begin to investigate this issue? Thanks a lothttps://e2echina.ti.com/support/sensors/f/sensors-forum/1091938/tmag5170-tmag5170-unexpected-behavioFri, 28 Aug 2026 12:33:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:a4126295-91b5-4de4-83fa-bc32f638ec1dzhenjun gaoPart Number: TMAG5170 Usage scenario: The TMAG5170 sensor board and ESP32‑C6 board are connected via approximately 10 cm ordinary wires. When a magnet with a magnetic‑field strength of about 60 mT is brought close to and moved away from the sensor standalone, magnetic‑field variations can be detected by the sensor. Overshoot is observed on the clock signal during tests, which is improved by adding a series‑connected 33 Ω resistor. It is a 2‑layer PCB as shown in the figure below. Is the PCB layout unreasonable? With the sensor board mounted between two magnets, the SPI SCLK is pulled down to around 1 V. No output is present on SPI MISO, whereas MOSI and CS waveforms look normal. See the figure below for the clock signal.TMAG5170便携式电子产品https://e2echina.ti.com/support/clock-and-timing/f/clock-timing-forum/1091937/lmx2594-lmx2594-automatic-ramping-mode/3930116Fri, 28 Aug 2026 09:51:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:29d6ef85-f938-4105-bc53-87a1bf9af7beLinks您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/clock-and-timing/f/clock-timing-forum/1091937/lmx2594-lmx2594-automatic-ramping-modeFri, 28 Aug 2026 09:40:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:cdf2be6c-5319-4ac4-a792-4322919cf4bflizeng dongPart Number: LMX2594 您好！ 我们需要使用LMX2594生成10700MHz~11700MHz和11800MHz~12800MHz的线性扫频，现在是利用两颗LMX2954各自负责一个频段的线性扫描。目前我们进行的测试都是在10700MHz~11700MHz频段，我们想要的是在这个频段内任意设置带宽(1MHz~1000MHz)输出线性扫频。现在我测试了100MHz的带宽，输出结果基本满足。在测试200MHz带宽时测试了很多参数(参数时使用TICS Pro工具生成)，都会出现线性扫频扫不出一段高频率的信号。以下是我的配置截图和测试结果截图。 测试1：10700MHz~10800MHz 测试2：10600MHz~10800MHz 示波器监测的是芯片的35脚Vtune的电压 就上述现象，有以下几点需要贵司确认。 ①.在我配置中是否存在不合理的参数，影响是什么？需要怎么解决？ ②.关于带宽200M及以上需要怎么配置？是否有需要手动修改的寄存器参数，还是使用TICS Pro工具配置就能完成业务？ ③.扫频信号是从10700MHz~11700MHz，在扫描时会选择不同的VCO，这样VCO的校准是否不可避免？实际扫频持续时间就会和设置扫频持续就会相差很多？我也试过在1000MHz带宽时把Threshole 参数设置为1000，但是实际扫频输出和预想相去甚远，看起来像是点频。 我测试是使用自己的硬件，没有官方硬件。望尽快回复，谢谢！lmx2594无线基础设施https://e2echina.ti.com/support/power-management/f/power-management-forum/1091936/tps62843-what-s-the-difference-between-tps628438ykar-a-with-and-without-the-aFri, 28 Aug 2026 09:22:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:f1427e8d-8c18-4502-9369-43283ac0f319xc tPart Number: TPS62843 What's the difference between TPS628438YKAR.A with and without the ".A"?TPS62843医疗和保健https://e2echina.ti.com/support/audio/f/audio-forum/1091923/opa2134-opa2134ua-2k5-ib/3930115Fri, 28 Aug 2026 08:59:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:968da2de-a5a0-4f8c-adc6-21da3774523aEirwen请按照以下链接联系客户支持中心，会有客服为您提供帮助： ticsc.service-now.com/csmhttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1091932/mspm0-sdk/3930114Fri, 28 Aug 2026 08:56:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:ff4df3ca-eddb-4763-a332-36952fae2d34Eirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1091920/drv8701-drv8701-/3930113Fri, 28 Aug 2026 08:55:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:423d7799-bf86-42e6-9a32-7f069292ff0bEirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/logic/f/logic-forum/1091926/cd4013b/3930112Fri, 28 Aug 2026 08:53:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:50379031-d487-49d6-b05e-6b5f6ae0ffccEirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。
