USB4 architecture (formerly known as Thunderbolt 3 protocol) is a transformational
high-speed, dual protocol I/O, and it provides flexibility and simplicity by
encapsulating both data (PCIe* & USB3) and video
(DisplayPort*) on a single cable connection that can daisy-chain up to six devices.
USB4/Thunderbolt controllers act as a point of entry or a point of exit in the USB4
domain. The USB4 domain is built as a daisy chain of USB4/Thunderbolt enabled
products for the encapsulated protocols - PCIe, USB3 and DisplayPort. These protocols
are encapsulated into the USB4 fabric and can be tunneled across the domain.
USB4 controllers can be implemented in various systems such as PCs, laptops and
tablets, or devices such as storage, docks, displays, home entertainment, cameras,
computer peripherals, high end video editing systems, and any other PCIe based
device that can be used to extend system capabilities outside of the system's box.
The integrated connection maximum data rate is 20.625 Gbps per lane but supports
also 20.0 Gbps, 10.3125 Gbps, and 10.0 Gbps and is compatible with older
Thunderbolt
™
device speeds.
USB 4 Host Router Implementation Capabilities

• Up to two DisplayPort* sink interfaces each one capable of:
— DisplayPort 1.4 specification for tunneling
— 1.62 Gbps or 2.7 Gbps or 5.4 Gbps or 8.1 Gbps link rates
— x1, x2 or x4 lane operation
— Support for DSC compression
• Up to two PCI Express* Root Port interfaces each one capable of:
— PCI Express* 3.0 x4 compliant @ 8.0 GT/s
• Up to two xHCI Port interfaces each one capable of:
— USB 3.2 Gen2x1 (10 Gbps)
• USB 4 Host Interface:
— PCI Express* 3.0 x4 compliant endpoint
— Supports simultaneous transmit and receive on 12 paths
— Raw mode and frame mode operation configurable on a per-path basis
— MSI and MSI-X support
— Interrupt moderation support
• USB 4 Time Management Unit (TMU):
• Up to two Interfaces to USB-C* connectors, each one supports:
— USB4 PD entry mode, as well as TBT 3 compatibility mode, each supporting:
• 20 paths per port
• Each port support 20.625/20.0 Gbps or 10.3125/10.0 Gbps link rates.
• 16 counters per port
