My client is currently using the ADuM6000. Apparently after conducting RF Emission testing @ 360MHz their end product is not passing and they believe they have "pinpointed" the emissions coming from the ADuM6000. They also ordered the ADuM6000 eval board and tested it with a 7mA load and RF emission is the same as their board @ 360 MHz. According to them they have followed AN-0971. Any suggestions or tips would be greatly appreciated. Thanks
Best to provide schematics and layout to be able giving recommendations.
The ADuM6000 is an isoPower device and as described in AN-0971 will have emissions at 180MHz on the primary side due to the tank circuit frequency, and at 360MHz on the secondary side due to the rectifying frequency of the isolated DC to DC converter. AN-0971 recommends the use of stitching capacitance for the most reduction in emissions. It would be best to review their layout and schematics, as suggested here. Sharing these documents could be done by email privately if desired.
Awesome, thanks Brian. I will ask them to do so.
