USB 3.0 – The Next-Generation Interconnect
Introduction Have you ever had a moment when you were annoyed by technology that was not fast enough? Let's look at a scenario that could happen: your flight from San Francisco to New York is scheduled to depart in three hours. You are ready to go towards the airport. However, you really would like to catch up on the latest season of your favourite show "House" that you haven't seen. A friend has sent you an email via Facebook about how they enjoyed a blockbuster film he saw last night , and you would like to watch it while on the long flight you're about to embark on. If I were you I'd be thinking "if only I could just access all the content I require today". It takes around 14 minutes to transfer the HD film of 25GB, and nearly nine minutes for transferring a television Show that is 16GB in size from a computer to your handheld media device. The good news is that technological advancements are occurring at a rapid pace that allow users to access the content they desire much faster. One of these developments is the one that uses the most widely used and universal interface known to mankind - USB. USB 3.0 SuperSpeed is here and is expected to be the solution for such issues. The history of USB In the age of the technology and communication huge amounts of content is being created and consumed, processed and accessed at an alarming rate. simultaneously the mass storage technology is being transformed in a significant way. Storage is becoming less expensive and density is increasing and driving the sharing of content. People no longer have to have to worry about preserving the space on their hard drives. The photography life is much easier when you have multiple storage cards that allow you to easily click numerous photos and swap out cards when they are full. Visit:- https://darioitem.digital/ These models of usage are getting more popular, not only in the corporate and professional setting as well as in the market for consumers. Camcorders and still cameras are moving toward higher resolution and better quality images, resulting in the need for a speedier connection to take advantage of the contents. This is so urgent the need for a faster connection that a number of technology experts have joined forces to address this issue in a stylish and seamless way. It is the USB Implementers Forum recognized this urgent need for the next generation of interconnect technology, and officially ratified the USB 3.0 specification in November of 2008. Comparative analysis with different Interfaces A variety of other standards for serial communication have a speed similar to the one in USB 3.0. For instance, PCIe Gen 2.0 has 5Gbps of data speed as well. Serial ATA (SATA) III is a speed of 6Gbps. While it is true that the USB 3.0 PHY architecture has its roots by PCIe, a few important distinctions are left out. It is important to note that the USB 3.0 PHY has to implement an equalizer to compensate for loss of cable. This permits USB cables to extend up to three meters. It is important to note that the PCIe as well as SATA PHYs don't have this equalizer. The LFPS feature mentioned earlier is not available on this USB 3.0 PHY. A PCIe link could comprise of several lanes (i.e. two transmit and receive differential lines) to boost bandwidth, while the USB 3.0 link can only support one lanes. Of the three interfaces, plug and play can be enabled only via USB. The SATA standard supports hot-plug, however it is dependent upon the SATA controller operating within Advanced Host Controller Interface (AHCI) mode. PCIe is utilized to link peripheral functions card (such graphics cards) directly to the motherboard of the PC.SATA is a preferred interface preference for large storage devices like optical and hard disk drives. This is why the majority of PCs come with an SATA host adapter. USB however is a general-purpose SuperSpeed Bridge, also known as Hi-Speed between the host and almost any interface. USB 3.0 is also a good choice to serve as an alternative interface to transfer video due to the higher bandwidth. It could lead to some exciting applications for the digital living space which include television, STB, monitors as well as gaming consoles. The main benefit of USB over video interfaces such as VGA DisplayPort, DVI, and HDMI is the widespread availability that the connection. With HDCP 2.0 with USB among the available interfaces protection of content can be enabled via USB 3.0. Another advantage is that USB is royalty-free. USB Charging Charging is one of the key features that is distinctive when you compare USB against other interfaces. USB is currently the charging interface of choice in a variety of countries. Charging via USB offers many advantages in comparison to having separate chargers for each device. It not only reduces costs of manufacturing by restricting the use of specific chargers for a particular vendor, but it can also have a significant environmental impact in the longer run.USB 3.0 hubs and hosts allow battery charging according to the USB Battery Charging Specification. The USB Battery Charging Specification currently provides three different charging modes - 1. Host Charger : A host charger is an USB 2.0 host that can supply up to 500mA of power to a downstream port and incorporates charger detection. Hi-Speed devices can draw only up to 9000mA from the host charger. 2. Hub Charger Hub Charger an USB 2.0 hub which can supply up to 500mA of power to an outgoing port and also supports charging detection. The charging function is like a host charger. 3. dedicated charger – A charger that can provide power via USB interface, but it does not identify the device. The charging power is restricted to 1.5A.The specification also allows for dead battery charging, which allows the dead or fragile battery to be able to pull up to 100mA from the hub host until it is fully charged to an acceptable level. The main benefit of being capable of charging over USB is that it can be utilized in USB 3.0 devices. Conclusion: USB 3.0 is expected to become the most widely used solution for a variety of bandwidth-hungry applications. The evolution of the previously popular USB 2.0 is fueled by the increasing demands for multimedia and the development of higher density storage technology. USB 3.0 is certainly a technology catalyst in the hype cycle and must prove that it is able to get past the peak of expectations that are exaggerated, leading to widespread market acceptance. The day is rapidly approaching when you will be able to access all the information you need while you are at the airport, in less than one minute.
