1.1 Scope of the Document The specification is primarily targeted at peripheral developers and platform/adapter developers, but provides valuable information for platform operating system/BIOS/device driver, adapter independent hardware vendors/independent software vendors, and system OEMs. This specification can be used for developing new products and associated software. 1.2 USB Product Compliance Adopters of the USB4™ specification have signed the USB4 Adopters Agreement, which provides them access to a royalty-free reasonable and nondiscriminatory (RAND) license from the Promoters and other Adopters to certain intellectual property contained in products that are compliant with the USB4 specification. Adopters can demonstrate compliance with the specification through the testing program as defined by the USB Implementers Forum (USBIF). Products that demonstrate compliance with the specification will be granted certain rights to use the USB-IF logos as defined in the logo license. 1.3 Document Organization Chapters 1 and 2 provide an overview for all readers, while Chapters 3 through 13 contain detailed technical information defining USB4. 1.4 Design Goals USB 3.1 and USB 3.2 were evolutionary steps to increase bandwidth. The goal for USB4 remains the same with the added goal of helping to converge the USB Type-C® connector ecosystem and minimize end-user confusion. Several key design areas to meet this goal are listed below: - Offer display, data, and load/store functionality over a single USB Type-C connector. - Retain compatibility with existing ecosystem of USB and Thunderbolt™ products. - Define Port Capabilities for predictable and consistent user experience. - Provide increased host flexibility to configure bandwidth, power management, and other performance-related parameters for system needs. 1.5 Related Documents Universal Serial Bus 3.2 Specification, Revision 1.0, September 22, 2017 (USB 3.2 Specification) USB Type-C® Cable and Connector Specification, Release 2.0 (USB Type-C Specification) USB 3.0 Jitter Budgeting white paper (USB Jitter Paper) Universal Serial Bus Power Delivery Specification, Release 3.0, Version 2.0, August 2019 (USB PD Specification) PCI Express® Base Specification, Revision 4, Version 1, September 27, 2017 (PCIe Specification) VESA DisplayPort™ Standard, Revision 1.2a, May 2012 (DisplayPort 1.2a Specification) VESA DisplayPort™ Standard, Revision 1.4a, April 19, 2018 (DisplayPort 1.4a Specification) VESA DisplayPort™ 1.4a PHY Layer Compliance Test Specification, Revision 1.0, 27 July, 2018 (DisplayPort 1.4a PHY CTS) VESA DisplayPort™ Alt Mode on USB Type-C Standard, Revision 1.0b, November 03, 2017 (DisplayPort Alt Mode Specification) eXtensible Host Controller Interface for Universal Serial Bus, Revision 1.1 (xHCI Specification) USB4 Connection Manager (CM) Guide, Revision 1.0, [to be published] – (Connection Manager Guide) USB4 Re-Timer Specification, [to be published] – (USB4 Re-Timer Specification) USB4 Device ROM (DROM) Specification, Revision 1.0, [to be published] – (USB4 DROM Specification) USB4 Inter-Domain Specification, Revision 1.0, [to be published] – (USB4 Inter-Domain Specification) HDCP on DisplayPort™ Specification, Revision 2.3, January 22, 2019 (HDCP Specification)
