6.0 USB-C* Sub System
USB-C* is a cable and connector specification defined by USB-IF.
The USB-C sub-system supports USB3, USB4, DPoC (DisplayPort over Type-C)
protocols. The USB-C sub-system can also support be configured as native DisplayPort
or HDMI interfaces, for more information refer to Display on page 153.
Thunderbolt
™
4 is a USB-C solution brand which requires the following elements:
• USB2, USB3 (10 Gbps), USB3/DP implemented at the connector.
• In additional, it requires USB4 implemented up to 40 Gbps, including Thunderbolt
3 compatibility as defined by USB4/USB-PD specs and 15 W of bus power
• Thunderbolt 4 solutions use (and prioritize) the USB4 PD entry mode (while still
supporting Thunderbolt 3 alt mode)
• This product has the ability to support these requirements
NOTE
If USB4 (20 Gbps) only solutions are implemented, Thunderbolt 3 compatibility as
defined by USB4/USB-PD specs and 15 W of bus power are still recommended
General Capabilities
• xHCI (USB 3 host controller) and xDCI (USB 3 device controller) implemented in
the processor in addition to the controllers in the PCH.
• No support for USB Type-A on the processor side, For USB Type-A implementation
and capabilities refer to PCH Datasheet Vol1.
• Intel AMT/vPro over Thunderbolt docking.
• Support power saving when USB-C* disconnected.
• Support up to four simultaneous ports.
• DbC Enhancement for Low Power Debug until Pkg C6
• Host
— Aggregate BW through the controller at least 3 GB/s, direct connection or over
USB4.
— Wake capable on each host port from S0i3, Sx: Wake on Connects,
Disconnects, Device Wake.
• Device
— Aggregate BW through xHCI controller of at least 3 GB/s
— D0i2 and D0i3 power gating
— Wake capable on host initiated wakes when the system is in S0i3, Sx Available
on all ports

• Port Routing Control for Dual Role Capability
— Needs to support SW/FW and ID pin based control to detect host versus
device attach
— SW mode requires PD controller or other FW to control
• USB-R device to host controller connection is over UTMI+ links.
