DS90UB913A-Q1: Recommended ferrite beads

NOBUO FUJIHARA

Part Number: DS90UB913A-Q1

Hello,

My customer is struggling to improve spurious radiated from Serializer.

As workaround, customer is planning to put FB on VDDPLL and VDDCML line as shown Figure 36,

Does this really help to reduce spurious which is mainly coming from PLL, and could you provide exact parts number of recommended ferrite beads?

Best regards,

Hi Manickam,

This post is related to the E2E thread which is moved to offline.

Customer requirs advices to reduce EMI and Ferrite beads information ASAP, I realy need quick support.

And this specific requirement does not contain customer's confidential information.

That is why I put this specific requrest on E2E not adding to offline request.

Would you support this?

Best Regards,

Since this is related to the other thread on the same EMI topic being handled offline, I'd suggest you add this question there and we can close this thread.
