The new version of USB (USB 3.0), whose standards were issued in November 2008, has received over the previous version (USB 2.0) some significant improvements. The main advantages of the new interface is a high speed up to 5 Gbit/s, advanced power bus management and backward compatibility with previous USB versions. Thunderbolt technology is in these days another very perspective and competitive interface combining the features of PCI-Express Interface and Display Port. There is available an interesting comparison with USB 3.0 interface.


Students will learn the basic principles and characteristics of perspective USB 3.0 and Thunderbolt interfaces. He obtains knowledge of the interface operation modes by describing of the various layer models. The main focus is on protocol layer. The module also describes the differences in comparison with previous versions of interfaces and backward compatibility with them.
