DS90UB949-Q1: question about DS90UB949-Q1

Hello：

The customer needs to conduct EMC testing and needs to enable the spread spectrum function within 949, but they do not know how to enable it

I would like to know if it is necessary to operate on IN-CLK+/- pins 49/50? Or is it a register operation method? Please provide guidance, thank you!!!

Hello Jimmy,

due to a public holiday in the U.S., the whole team is out and will be back on Monday.

Hi Jimmy,

Is this referring to SSC on the HDMI input? The datasheet shows the SSC tolerance and what is supported, and there is no register setting needed for this.

Could you tell us which SoC is being used to send the SSC video? The SoC's spread spectrum clock generation should be within the 949 tolerance.

Best regards,
Ikram
