Technology and components

This chapter details the technology and components available in the system.

Topics:

•DDR4

•USB features

•HDMI

DDR4

DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512 GB in capacity, compared to the DDR3's maximum capacity of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is keyed diferently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.

DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down mode is expected to reduce standby power consumption by 40 to 50 percent.

Key Speciications

The following table lists the speciications' comparison between DDR3 and DDR4:

DDR4 Details

There are subtle diferences between DDR3 and DDR4 memory modules, as listed below.

Key notch diference

The key notch on a DDR4 module is in a diferent location from the key notch on a DDR3 module. Both notches are on the insertion edge, but the notch location on the DDR4 is slightly diferent, to prevent the module from being installed into an incompatible board or platform.

Figure 1. Notch diference

Increased thickness

DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.

Figure 2. Thickness diference

Curved edge

DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.

Technology and components

USB features

Universal Serial Bus, or USB, was introduced in 1996. It dramatically simpliied the connection between host computers and peripheral devices like mice, keyboards, external drivers, and printers.

Let's take a quick look on the USB evolution referencing to the table below.

Table 2. USB evolution
Type	Data Transfer Rate	Category	Introduction Year

USB 2.0	480 Mbps	High Speed	2000
USB 3.0/USB 3.1 Gen 1	5 Gbps	Super Speed	2010
USB 3.1 Gen 2	10 Gbps	Super Speed	2013

USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)

For years, the USB 2.0 has been irmly entrenched as the de facto interface standard in the PC 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 inally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1 features are as follows:

•Higher transfer rates (up to 5 Gbps)

•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 USB 2.0 compatibility

•New connectors and cable

The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.

Speed

Currently, there are 3 speed modes deined by the latest USB 3.0/USB 3.1 Gen 1 speciication. They are Super-Speed, Hi-Speed and FullSpeed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the speciication retains Hi-Speed, and Full-Speed USB mode,

10 Technology and components

commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward compatibility.

USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:

•An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).

•USB 2.0 previously had four wires (power, ground, and a pair for diferential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs of diferential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.

•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-deinition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this speed, USB 3.0/USB 3.1 Gen 1 is a 10x improvement over USB 2.0.

Applications

USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will ind its way into some products that previously weren't USB territory, like external RAID storage systems.

Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:

•External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives

•Portable USB 3.0/USB 3.1 Gen 1 Hard Drives

•USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters

•USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers

•USB 3.0/USB 3.1 Gen 1 Solid-state Drives

•USB 3.0/USB 3.1 Gen 1 RAIDs

•Optical Media Drives

•Multimedia Devices

•Networking

•USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs

Technology and components

Compatibility

The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB 3.0/USB 3.1 Gen 1 speciies new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only come into contact when connected to a proper SuperSpeed USB connection.

Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.

Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service Pack or update. It is not out of the question to think that following a successful release of USB 3.0/USB 3.1 Gen 1 support in Windows 7, SuperSpeed support would trickle down to Vista. Microsoft has conirmed this by stating that most of their partners share the opinion that Vista should also support USB 3.0/USB 3.1 Gen 1.

HDMI

This topic explains the HDMI 2.0 and its features along with the advantages.

HDMI (High-Deinition Multimedia Interface) 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-deinition video, plus multichannel digital audio on a single cable.

NOTE: The HDMI 1.4 will provide 5.1 channel audio support.

HDMI 2.0 Features

•HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing 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 built-in tuner to send audio data "upstream" to a surround audio system, eliminating the need for a separate audio cable

•3D - Deines 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 picture settings based on content type

•Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics

•4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital Cinema systems 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, 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-efective 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 currently used in A/V systems
