TUSB212: Should I short D2P/N to D1P/N on PCB

Part Number: TUSB212

Dear TI,

In the datasheet, it seems D2P/N should be shorted to D1P/N on PCB, could you please explain more? I am curious how the signal conditioning function can be achieved is input and output are shorted. Thank you very much.

    Hi,

    TUSB212 uses proprietary edge booster technology that allows the trace to short underneath the device to boost the signals. TUSB212 compensates for the losses to the USB 2 packet as it traverses the transmission media. TUSB212 includes options to tune the transition bits (AC Boost) and non-transition bits (DC Boost) separately.
