Dear Sir,
ADM3054 1MHz Emission fails
We are using ADM3054 for Can isolation transiver.
From Our EMC emission test , we can see every 1MHz noise (which over some limit line on 100MHz)
After some investigation , we have find ADM3054 make this noise.
- With Near field probe , ADM3054 make 1Mhz noise
- Check LISN and 5V line of ADM3054 VDD2, we find it as attaced.
I am not familiar with the internal architecture of ADM3054.
Why AMD3054 make this noise?
From ADM3054 datasheets, It's seem there is no active switching components on ADM3054.
I hope your helps.
Best Regards,
