The other CC pin is repurposed as V CONN for powering electronics Also, only one set of USB 2.0 D+/D- wires are implemented High Speed Data Path High Speed Data Path USB 2.0 Cable Bus Power Sideband Cable Configuration (RX for USB 3.1, or (TX for USB 3.1, or (from 5V up to 20V) reconfigured in Alternate Mode) reconfigured in Alternate Mode) Interface use Ground Channel USB-C: Host-to-device Connection 9 SOURCE SINK (Host / DFP) (Device / UFP) 4 possible Source Rp wiring Sink Rd Power pull-up pull-dw Legacy current 56 k Ω CC pin 5.1 k Ω 1.5A @ 5V 22 k Ω 3A @ 5V 10 k Ω 1.

At insertion detect, the Configuration Channel (CC pin) is used to solve plug orientation (CC1 or CC2) • HOST identified by Pull-up resistor / current source on its CC pin • Device identified by Pull-Down resistor on CC pin 3. After correct Host to Device connection, VBUS is supplied as well as Vconn on the unconnected CC pin 4.

  • USB-IF Announces Publication of USB4™ Specification Specification Now Available for Download on USB-IF Website; Doubles Bandwidth to Extend USB Type-C® Performance
    DEVELOPER UPDATE CONTACT: Joe Balich USB-IF PR +1 503-619-4113 [email protected] USB-IF Announces Publication of USB4™ Specification Specification now available for download on USB-IF website; doubles bandwidth to extend USB Type-C® performance Beaverton, OR, USA – September 3, 2019 – USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4™ specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt™ protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols. The development of the USB4 specification was first announced in March 2019 by the USB Promoter Group. It is now officially published by USB-IF and available for download at www.usb.org. Key characteristics of the USB4 solution include: • Two-lane operation using existing USB Type-C® cables and up to 40Gbps operation over 40Gbps certified cables • Multiple data and display protocols that efficiently share the maximum aggregate bandwidth • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3 As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.

General Information Introduction Eliminate the confusion surrounding the Type-C connector with a dock that adapts to the interface it is connected to. Thunderbolt 3 and USB-C share the same connector, and up until now Thunderbolt 3 devices have only worked on Thunderbolt 3 host laptops, creating confusion for many users. The USB-C HDMI Dock breaks this mould by utilizing the latest Thunderbolt technology to adapt itself to your laptop. It is essentially a full Thunderbolt 3 (40Gb/s) device that has the latest Thunderbolt advancements in order to be compatible with non-Thunderbolt 3 laptops that feature USB-C. In addition, the USB-C HDMI Dock is also compatible with Thunderbolt 4 computers. Now everyone can benefit from a feature rich dock without compromising on connectivity and compatibility. 3 General Use Warnings • Please read the USB-C HDMI Dock manual thoroughly and familiarize yourself with the product before use. • Avoid using the USB-C HDMI Dock in extremely hot and cold environments. A safe temperature range is between 40°F – 95°F (4.4°C - 35°C). • Avoid using the USB-C HDMI Dock in humid environments. Moisture and condensation can accumulate in the device and cause damage to the electrical components.
