Hello team,

The EMI peak frequency components when 947 - 948 is linked is below, correct?

EMI peak frequency component = N x fPCLK
N = 1, 2, 3... (natural number)
fPCLK = frequency of pixel clock

Are there any other EMI frequency components we expect specifically?

Thanks.

Hi Hirata-san,

Forward channel frequency (PCLKx35)/2 and back-channel frequency (5Mbps/10Mbps/20Mbps depending on BC_FREQ_SELECT - divide by two for MHz) would be the main two frequency components.

Logan
