EMI from TRK-KEA128 development boarrd

[nirmalakunwar]

Hi,

I am using TRK_KEA128 development board in my system, where it will be part of a bigger automotive system. While checking EMI levels for board over range of frequencies I found quite high amplitude (36-40 dBuV) of EMI at micro-controller clock frequency and its harmonics. I have tested it with both internal and external clock with frequencies ranging from 5Mhz to 50Mhz and observed EMI at all clock frequencies and their harmonics. It will be great if I can get a test document of the KEA128 board with EMI values at various frequencies so that I will have a benchmark to compare and analyse.

Hi Nimala

We have some report for the KE128 regarding EMI but those information is under NDA.

You can create a case support on

Sales and Support|NXP

under handware & software

And ask for this report, just you need to have NDA already signed

If you have a FAE (field application engineer) please ask him about how to sign the NDA.

If you already have a NDA id your put it on the case that you create.

Once you have the case number please send it to me, and I will check that we will send you the report.
