Hi,

There is the following picture on the datasheet.

Could you tell me why does AC coupling capacitor of RXP/N2 disappear?

Best Regards,

Kuramochi

    Hello Kuramochi-san,

      They didn't disappear; per USB3 specification each transceiver must have its own AC caps, therefore in the figure ome AC caps pair belongs to the Host TX, the second pair belongs to the Re-driver TX on the host side, and the third one belongs to the Re-driver TX on the connector side. The appearing missing AC caps pair is on the device, on the other side of the USB3 cable.

    Regards,

    Diego.
