Fundamentals of Thunderbolt 3 Architecture
This webinar provides a brief introduction to Thunderbolt 3 technology. Thunderbolt 3 is an Intel-defined hardware interface supporting very high bandwidth IO data and the ability to provide up to 100W of DC power—all using a single cable between a host computer and an attached device, dock, etc. Thunderbolt 3 employs the same small Type-C receptacles/plugs already found in USB devices ranging from cell phones and tablets up to large workstations and servers. A goal of Thunderbolt 3 coupled with Type-C is to provide a single connection that can “do it all”. Depending on the capabilities of attached devices and cables, the actual data protocol used on a particular port may be Thunderbolt 3 at 40 Gb/s or 20 Gb/s, one of the five possible USB 2.0/3.0/3.1 protocols and speeds, or one of the other Type-C alternate modes, including Display Port 1.2, HDMI, MHL (Mobile HD Link), etc. In this webinar, we are primarily concerned with Thunderbolt 3 (40 Gb/s or 20 Gb/s)—the highest performance protocol available on Type-C.
Using the same Type-C receptacles and plugs for USB 3.1 and the Type-C alternate modes (including Thunderbolt 3) adds some complexity to the scenarios a user may encounter when making device connections. This is compounded by an expanding set of active and passive USB Type-C and Thunderbolt 3 cables—all of which are similar in appearance, but have different protocol, speed, and power capabilities.
The goal of this webinar is to summarize the basic elements of Thunderbolt 3, with an emphasis on ports operating at 40 Gb/s and 20 Gb/s Thunderbolt 3 modes and shed light on the important features (and possible areas of confusion) associated with this very high performance interface.
