TUSB2046B: TUSB2046B

Part Number: TUSB2046B

Tool/software:

I am using the TUSB2046 as a hub for several on board devices.

The board is 2 layer

The bottom layer is poured as a ground plane

2 of the diff pairs are also on the bottom layer as highlighted in white on the photo

Will this cause signal integrity issues?

  • Hi Bruce:

      High-speed signals should be routed over a solid GND reference plane so you have a return path. so please route high speed on top layer .

    Best
