The industrial AI edge gateway supports desensitization of sensitive information such as faces and license plates in images and videos before AI inference. The desensitization algorithm runs on the NPU, and its power consumption and current changes may cause power supply noise. It is recommended to connect a TVS 5.0SMDJ33CA and a PBZ1608E600Z0T ferrite bead in parallel to the NPU power supply. At the same time, the DDR desensitization buffer power supply uses a common mode inductor CML3225A-101T for filtering. The actual measured desensitized AI inference frame rate is 25fps and the power ripple is 24mV, which is privacy compliant and EMC qualified.
