Technology and components
This chapter details the technology and components available in the system.
Topics:
• USB features
• USB Type-C
• HDMI 2.0
• Corning Gorilla Glass
USB features
Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host system units and
peripheral devices like mouses, keyboards, external drivers, and printers.
Table 1. USB evolution
Type Data Transfer Rate Category
USB 2.0 480 Mbps High Speed
2
USB 3.2 Gen 1 5 Gbps SuperSpeed USB 5 Gbps
USB 3.2 Gen 2 10 Gbps SuperSpeed USB 10 Gbps
USB 3.2
For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the personal computer world with about
6 billion devices sold, and yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth
demands. The USB 3.0/USB 3.1 Gen 1 finally has the answer to the consumers' demands with a theoretically 10 times faster
than its predecessor. In a nutshell, USB 3.2 features are as follows:
● Higher transfer rates (up to 20 Gbps).
● Increased multilane operation of 10 Gbps each.
● Increased maximum bus power and increased device current draw to better accommodate power-hungry devices.
● New power management features.
● Full-duplex data transfers and support for new transfer types.
● Backward compatibility with USB 3.1/3.0 and USB 2.0.
● New connectors and cable.
Speed
● The USB 3.2 provides three transfer rates:
○ USB 3.2 Gen 1 (5 Gbps)
○ USB 3.2 Gen 2 (10 Gbps)
○ USB 3.2 Gen 2x2 (20 Gbps)
● The marketing names below indicates the performance signaling that a product delivers in the product packaging, and any
other marketing materials:
○ SuperSpeed USB 5Gbps—product signals at 5 Gbps
○ SuperSpeed USB 10Gbps—product signals at 10 Gbps
○ SuperSpeed USB 20Gbps—product signals at 20 Gbps
Technology and components 7
NOTE:
● USB 3.2 protocol specification defines only the performance capabilities that may be implemented in a product.
● USB 3.2 is not USB Power Delivery or USB Battery Charging.
USB Type-C
USB Type-C is a new physical connector. The connector itself can support various exciting new USB standards.
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. USB Type-C ports can support a variety of different
protocols using “alternate modes,” which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types
of connections from that single USB port
USB Power Delivery
The USB PD specification is also closely intertwined with USB Type-C. Currently, smartphones, tablets, and other mobile
devices often use a USB connection to charge. A USB 2.0 connection provides up to 2.5 watts of power — that'll charge your
phone, but that's about it. A laptop might require up to 60 watts, for example. The USB Power Delivery specification ups this
power delivery to 100 watts. It's bi-directional, so a device can either send or receive power. And this power can be transferred
at the same time the device is transmitting data across the connection.
This could spell the end of all those proprietary laptop charging cables, with everything charging via a standard USB connection.
You could charge your laptop from one of those portable battery packs you charge your smartphones and other portable devices
from today. You could plug your laptop into an external display connected to a power cable, and that external display would
charge your laptop as you used it as an external display — all via the one little USB Type-C connection. To use this, the device
and the cable have to support USB Power Delivery. Just having a USB Type-C connection doesn't necessarily mean they do.
Thunderbolt 3 over USB Type-C
Thunderbolt 3 brings Thunderbolt to USB Type-C at speeds up to 40 Gbps, creating one compact port that does it all delivering the fastest, most versatile connection to any dock, display or data device like an external hard drive. Thunderbolt 3
uses a USB Type-C connector/port to connect to supported peripherals.
1. Thunderbolt 3 uses USB Type-C connector and cables - It is compact and reversible
2. Thunderbolt 3 supports speed up to 40 Gbps
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. Thunderbolt, USB, DisplayPort and power on USB Type-C on a single cable (features vary between different products)
2. USB Type-C connector and cables which are compact and reversible
3. Supports Thunderbolt Networking (*varies between different products)
4. Supports up to 4K displays
5. Up to 40 Gbps
NOTE: Data transfer speed may vary between different devices.

HDMI 2.0
This topic explains the High-Definition Multimedia Interface (HDMI) 2.0 and its features along with the advantages.
HDMI is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any
compatible digital audio/video source, such as a DVD player, or A/V receiver and a compatible digital audio and/or video
monitor, such as a digital TV (DTV). The intended applications for HDMI TVs, and DVD players. The primary advantage is cable
reduction and content protection provisions. HDMI supports standard, enhanced, or high-definition video, plus multichannel
digital audio on a single cable.
HDMI 2.0 features
● HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, enabling users to take full advantage of their IP-
enabled devices without a separate Ethernet cable
● Audio Return Channel - Allows an HDMI-connected TV with a integrated tuner to send audio data "upstream" to a
surround audio system, eliminating the need for a separate audio cable
● 3D - Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater
applications
● Content Type - Real-time signaling of content types between display and source devices, enabling a TV to optimize
illustration settings based on content type
● Additional Color Spaces - Adds support for additional color models that are used in digital photography and computer
graphics
● 4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that rival the Digital Cinema
systems that are used in many commercial movie theaters
● HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up
to 1080p
● Automotive Connection System - New cables and connectors for automotive video systems, which are designed to meet
the unique demands of the motoring environment while delivering true HD quality
Advantages of HDMI
● Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
● Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video
formats in a simple, cost-effective manner
● Audio HDMI supports multiple audio formats from standard stereo to multichannel surround sound
● HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple
cables that are currently used in A/V systems
● HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality
