8 Layout

8.1 Layout Guidelines

1. An extra trace (or stub) is created when connecting between more than two points. A trace connecting pin

A6 to pin B6 will create a stub because the trace also has to go to the USB Host. Ensure that:

• A stub created by short on pin A6 (DP) and pin B6 (DP) at Type-C receptacle does not exceed 3.5 mm.

• A stub created by short on pin A7 (DM) and pin B7 (DM) at Type-C receptacle does not exceed 3.5 mm.

2. A 100-nF capacitor should be placed as close as possible to the TUSB322I VDD pin.
