DS90UB941AS-Q1: MT8666 and 941AS in the case of the spread-spectrum

Part Number: DS90UB941AS-Q1

Tool/software:

Hi team,

My customer is using 941AS with MT8666 SoC.

And recently they have faced the EMI issue and want to spread the spectrum of the DSI reference clock.

But the SoC vendor told them that MT8666 only can realize the spread spectrum at the lowest of ±1%.

And in the datasheet, we see that we can only accept at most 0.5%/±0.25%.

Do we have heard any solution in this combination? And do we have any solution from other customers? Can MT8666 realize the 0.5%/±0.25%?

Thanks a lot for your time and effort.

Looking forward to your reply.

BR,

Matt.
