2 Technology and components This chapter details the technology and components available in the system. Topics: • • • USB features USB Type-C HDMI 1.4 USB features Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheral devices like mice, keyboards, external drivers, and printers. Table 1. USB evolution Type Data Transfer Rate Category Introduction Year USB 2.0 480 Mbps High Speed 2000 USB 3.0/USB 3.
• USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold increase in theoretical bandwidth. With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.
Alternate Mode USB Type-C is a new connector standard that is very small. It is about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use.
3. DisplayPort 1.4 – compatible with existing DisplayPort monitors, devices and cables 4. USB Power Delivery - Up to 130W on supported computers Key Features of Thunderbolt 3 over USB Type-C 1. 2. 3. 4. 5.
• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality.
