DS90UH948-Q1: 32MHz 64MHz 96MHz EMI in 947/948

Part Number: DS90UH948-Q1

Hi Team,

We measure the 947/948 EMI performance and find there are 32MHz 64MHz 96MHz EMI noise on board.

We don't turn on the display, only turn on 947/948. PCLK = 75MHz, dual link

I only find the BISTC pin has 33MHz but we dont use the feature.

Do you have any idea which factor may cause the issue in 947/948 and how could I fix?

Regards,

Roy
