> Dear SI-gurus,

> I have a question about the ferrite bead we usually implement on the

> connecting Vdd to clock generator, is it for blocking the noise from clock
> generator that might go back into the power source and then into other
> devices that share that same power, or it is for blocking the noise from
> other device into clock generator? Or both ? And we found that on field
> measurement this ferrite bead seems to radiate a lot. Is it a natural
> consequence or we implement it the wrong way? Thanks in advance for any
