Other Parts Discussed in Thread: TPS2066C
Hi ,
I have read the application TUSB8040 Design Guide and application note mentions to use a Ferrite Bead on VBUS USB power line.
the Ferrite bead used is BLM18PG221SN1D with 220 ohms at 100MHz. Could you pls guide why did we select 100Mhz freq range instead of Selecting the Radiated EMI and Conducted EMI freq range.
Currently we are using USB 3.0 with Speed of 2.5GHz and would the Ferrite bead selected have any bad impact like lossy signals at operating USB Freq ?
Kindly suggest what other ferrite bead specification i should look for USB 3.0 application.
Regards
