Hi Team,

Please help to check if there is any problem for the design?

Customer found the speed cannot up to USB2.0 and USB3.0!

Thanks for the helping.

    Hi Peter,

    I am not seeing any major concerns upon first glance. A few suggestions - you only need capacitors on one side of the switch, so you can remove C5293&C5294.

    Could you clarify which power source is being used for VCC? Right now, the schematic shows two options (VDD3V3 & VIO18_PMU). There should only be one connected. Additionally, the RSVD pins are ok as long as VCC is tied only to VIO18_PMU. If VCC is tied to VDD3V3, the RSVD pins also need to be tied to VDD3V3.

    It is unclear from the original post if the customer is just requested a schematic review or is actually seeing an issue. If they are seeing an issue, could you please give specifics (voltages used, scope shots, what pins are seeing issues)?

    Thanks!
    Katy
