This section provides the timing specification for the USB3.0 (USB1 in the device) interface as a PCB design and manufacturing specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. TI has performed the simulation and system design work to ensure the USB3.0 interface requirements are met. The design rules stated within this document are targeted at DEVICE mode electrical compliance. HOST mode and/or systems that do not include the 3m USB cable and far-end 11-inch PCB trace required by DEVICE mode compliance testing may not need the complete list of optimizations shown in this document; however, applying these optimizations to HOST mode systems will lead to optimal DEVICE mode performance.
