Superspeed data channels.
▪ USB 2.0 data (480 Mbps) is transferred on
the High-speed data channels. The built-
in USB-Ethernet bridge provides Ethernet
connection over the USB-C connector. This
function uses the High-speed channels. For
more details see USB Port Diagram and Ethernet Interface section.
INFO: USB.2.x and 3.x data transfer happens on independent two layers simultaneously.
Displayport Alternate Mode (Video + Embedded Audio)
▪ DisplayPort Alternate Mode: Alternate mode
is designed for carrying uncompressed,
native Displayport video as a non-USB data
(All Superspeed Data lanes deliver video
signals, it reserves the whole bandwidth of
▪ DisplayPort Alternate mode and USB 3.1
data shared: and USB 3.1 data
are transmitted at the same time, shared
the bandwidth (2 SuperSpeed lines for
video + 2 SuperSpeed lines for USB 3.1).
