Hi Team,
I have a customer use 927/928 in infotainment. However they can't pass the EMC TEST. Because the over EMC point are 325.2MHz and 216.8MHz. As the output signal is 54.2MHz in 948.
54.2*6=325.2， 54.2*4=216.8， sixth harmonic and forth harmonic of signal of output in 948.
Does any precautionary measures of EMC in 947/948?
How to improve EMC in 947/948？
Their PCM and SCH is as following:
927:
928:
