USB 2.0 Research Paper
USB 1:
USB 1 is the first one established and realized in January 1996. It provided 1.5 Mb/s which is a low speed and 12 Mb/s which is a high speed transfer rates. Some of this data transfer rate is going for USB protocol so the exact data rate is less than the one above. Because of the limitation in timing and power, USB 1.0 did not allow for extension cables or pass-through monitors. Then USB 1.1 released in September 1998 to fix the problems related to using hubs that appeared in 1.0. This version adopted widely.
USB 2.0:
USB 2.0 is an evolution of the USB 1.1 in the year of 2000, which provided a transfer of high-speed rate and interface. It was a huge improvement of USB over the original speeds of USB 1.0. Today’s USB 1.1 connectors and similar cables will support the higher speeds of USB 2.0 without any changes. Characterization that …show more content…
In USB 2 the amount of power needed for unconfigured devices is 100mA while in USB 3 is 150mA. For configured devices, it is increased from 500ma to 900mA in USB 3.
USB 3.0 Physical Layer The physical layer on USB 3 defines the electrical characteristics of USB 3 signals such as how the information is scrambled and encoded, and how some signal sequences are used by different layers.
USB 3.0 Connectors
USB 3 connectors provide two main purposes. First one is that the connectors have to be able of physically interfacing with USB 3 signals. Second one, the connectors have to be compatible with cables of USB 2.
The applications that USB 3.0 enable
Briefly, different high-bandwidth device that is working with USB 2.0 will become better if it is provided with updated version on USB 3.0. USB 3.0 support more headroom for devices to produce a better overall user experience. If we compare a single-link DVI, we will find that it is requires almost 2Gbps throughput while 480Mbps was limiting, so 4.8Gbps is more than the required.
The extra performance in USB
