we are using a NVIDIA Jetson Xaviar AGX in our device. During a electromagnetic compatibility test a problem encountered if the HDMI interface was connected to the touch screen. The EMC test results are promising if we don’t use the HDMI connection.
Is there a way to manipulate the frequencies of the HDMI interface?
Is is possible to enable frequency spreading on HDMI?
Hi, what is your requirement on this? Are you using a devkit or custom design? Xavier devkit should not be used for a product. If a custom design, the PCB layout should follow the design guide well.
Our main requirement is, that we can pass the EN 61000-6-3. That norm defines the emitted interference. We are currently around 13dB above the maximum allowed peak.
We are not using the NVIDIA DevKit, we are using the Rogue Carrier board from ConnectTech.
