Head of the USB 3.0 standard USB standard 2.0, very, very well, the speed of transmission of the tributes. Specific USB 3.0 transfers SuperSpeed mode with fast transfer rates up to 5 Gbit / s (640 MB / s), so more than 10 times, which is changed to the one that is transferred to the specific USB 2.0. Oh, well, real swiftness transmissions of money to the future, shvidshe for everything, lower, protest with urahuvannya for great peripheral annexes such bandwidth USB bus 3.0 is more than enough.
It’s so very smart, like і be-like іnshe z'єdnannya. Note: if you get the lancers attached at once, do not forget to put the newest rose in the corner of your lancet, some transfer will only be added to the quicksilver of the newest component of your lancet. The procedure for attaching maє buti.
Does it mean ringing madness?
Port and cables constantly change. Zvorotna madness means you can connect more old version cable and attachment to the new port. Version 0 of the standard appeared at the site. Clients buli - and dosi - stumbled upon the minds of low quality, generally high speed, high speed and high speed.
Obviously, the speed of transmission from the USB 3.0 bus is not the same as from the USB 2.0 bus. Even with all the features (which are quite a lot), the speed of USB 3.0 with USB 2.0 can be saved.
That is in the specifics of USB 3.0, surrounded by SuperSpeed mode, unnecessary Hi-Speed, Full-Speed and Low-Speed modes.
In addition, USB 3.0 roses are superb with USB 2.0 roses. Tse means that all peripheral attachments USB interface 2.0 can be connected to USB 3.0.
However, it has a maximum speed of transmission, described in technical characteristics, little reach, tobto. rG. Protocol vitrati, one-hour access to the outbuildings on one bus, etc. At that hour, at the bottom of the parallel cables with wide 25-pin roses, the maximum amount of cables is surrounded by a ball. At six meters, buv kinets, as long as they did not reach the special cables, even more gliboko near the sumts.
At the points in the lower table, there is a maximum increase in performance for all versions of the universal last tire. The maximum zagalnaya dozhina, indicated at the table, can be increased by a path by adding six cables one to one stretching five. To change the maximum amount of food, you need special possession, for example.
It is important to consider the specifics of USB 3.0 from USB 2.0 to the fact that the standard transmits bi-directional transmission of data from twisted pair pairs. Thus, there are more contacts in USB 3.0 roses. The number of wires in the USB cable has been increased. So, in the USB 2.0 standard, one twisted pair was twisted for receiving / transmitting money, and for living, so that in USB 2.0 roses there were a lot of contacts, and a USB cable was used for receiving / transferring money. At the USB 3.0 specification, a pair is twisted to get stuck for transferring tributes, a friend - for receiving tributes, a third - for living, and for the sake of the USB 2.0 standard, a fourth twisted pair is transferred, for which to receive / transmit tributes USB modes 2.0 (Hi-Speed, Full-Speed and Low-Speed). Moreover, in the binding order, there is one more “ground” (GND_DRAIN) in the viglyad there are two twisted pairs. Thus, a USB 3.0 cable does not have any darts (like a USB 2.0 cable), but rather, but in USB 3.0 roses there are at least nine contacts (twisted pair braids are connected to the GND_DRAIN contact).
Besides, two screened differential bets, three darts can be taken from the skin: two for donations and one grounding wire. At the onset tables, they are re-insured by ci strumi in milliamps. As all attachments can be connected, the host can set its current line to the mode of low energy consumption.
9: Alternative interfaces
Don't be fooled by the way the robots are happy operating systemsі hard disk abo. The development of peripheral attachments, as you are on your skin day, as the official technologies are on your own, may be without any new interfaces. So you could have picked up the correct cable, you could have picked up the right cable, which you can buy from our store. Give you more information about the number of cables and interfaces, the axis of the look.
The strain of liveness, which is transmitted by the USB-bus, was lost without changes - +5 V.
Types of young roses and cables
Number of young rose'єmіv USB 3.0 is great. Є roses USB 3.0 advanced types: type A, type B, Powered-B, Micro-B, Micro-A and Micro-AB. Remarkably, pink USB 3.0 Micro-A is less for the plug version, and pink USB 3.0 Micro-AB is less for the connector. It is especially significant that the specifics of USB 3.0 are not transferred to miniUSB type B roses, as they are widely expanded on this day.
Types of young roses and cables
Tse vikoristovuєtsya for connection small annexes abo mobile annexes to the computer. Here the data is transmitted serіyno. Most of the cable technologies are often transmitted in parallel. Incomplete transmissions of the last tributes. Done codes for transmission in extra packets, and then code on the other attachment, some transmission will work through one cable in a cable. In such a rank, the transfer of tribute from the cable is more powerful, not with parallel transmissions, and that is less for the programs of the real hour. last version 0 transmitting data more quickly and can also transmit data in both directions in parallel! Reachings of the last transmission.
Rose USB 3.0 Type A.
USB 3.0 type A rose, both plug-in and socket, because of its shape and size cannot be referred to as USB 2.0 type A rose. Type A, except for USB 3.0 type A plug, USB 2.0 type A plug can be inserted, and packs: USB 2.0 Type A plug can be inserted into USB 3.0 type A plug.
Oscillated cables are stored in one transmission line, Minimized transmissions: in case of parallel transmission, especially with larger cables, there can be different modes of transmission between cables and, in such a rank, falsified data.
- The cables are thin and soft, the transmission of tributes is not parallel.
- Also, serial transmission cables can be significant.
Zagalom at roses USB 3.0 type A є nine pins.
The convenience of a USB 3.0 type A rose with a USB 2.0 type A rose can be reached from all the contacts present in a USB 2.0 type A rose, or in a USB 3.0 type A rose, but not without new contacts.
Rosem USB 3.0 Type B
Most laptops and computers also have an interface. Tse zagalny rose, with connected peripheral attachments to the computer. Keyboard, misha, modem, printer, scanner, etc. The price is connected to the annex. Zovnishniy printer hard drive or a scanner and connections to a connector on the annex.
Nabagato shvidsha transmission of tributes. ... The staff of the shvidk_y transmission danih New version Especially suitable for the transmission of great donations and donations, for which the transmission of the hour is important. We recommend you to take the instructions for the product. In addition to color gami, there is also a sense of technology, how to become victorious.
USB 3.0 type B rose, like USB 2.0 type B rose, vikoristov is available for connecting stationary peripheral attachments, such as printers, MFPs and call discs... Computers do not have USB 3.0 type B ports (as they do not use USB 2.0 Type B ports). Rose USB 3.0 type B, small box with rose USB 2.0 type B, so in female USB 3.0 type B, except for USB 3.0 type B plug, you can insert a USB 2.0 type B plug. And insert the axis into the USB 2.0 type B socket, the USB 3.0 type B plug will not fit.
However, through the sign of the transmission, the cable is especially suitable for calls hard drives, knitted adapters and attachments, such as digital cameras with great obligations of tribute. The cost of generation 0 and with such a rank I will fix the edge from the side of the attachment of the external cable.
The cable is mainly used for outbuildings with ample space, some roses can be distributed in the outbuildings through a small size. For mobile annexes, there is a mini-format, as it used to be great. Generation is required for even small portable attachments. Thus, the interface is now standard for smartphones in all great virobniks.
Zagalom at roses USB 3.0 type B є nine pins. The rosetting, naturally, occurs as the rosetting of contacts in USB 3.0 type A roses;
Rose'єm USB 3.0 Powered-B.
Rose USB 3.0 Powered-B for its form factor is more common with USB 3.0 type B, but instead of seeing two additional contacts in the living room (DPWR and DGND) and two additional cables, adapters without the need to connect them to the hem.
Rose and socket are also smart with the cable in the middle 0, but only allow the victorious power. The interface quickly became a standard rose for connecting analogue tributes. For children cable z'єdnan There are a lot of different versions, which are based on the number of poles and, also, there may be different sizes. Oskіlki cable transmission of data in analog mode, the second step is vikoristovuvati only for connecting analogue attachments. When connected to a computer, analog monitors are connected.
Digital cables transmit signals to the digital viewer. In addition, it is often the repetition of the tribute to produce to the deyakoi to spend tribute, well, at your own devil, means the destruction of the image. It is analogous and digital is parallel to the transmission of digital and analog signals. Besides, one or two signals can be transmitted one hour through a cable.
USB 3.0 Powered-B plugs accept USB 3.0 Powered-B plugs, USB 3.0 type B plugs and USB 2.0 type B plugs. All USB 3.0 Powered-B plugs are available with 11 pins.
Rose'єm USB 3.0 Micro-B.
Roz'em USB 3.0 Micro-B installation on a portable device for portable attachments, such as mobile phones, komunikatori and in. It is smart from the USB 2.0 Micro-B socket, to the USB 3.0 Micro-B socket, except for the USB 3.0 Micro-B plug socket, you can also insert the USB 2.0 Micro-B socket socket. However, it is not possible to insert a USB 3.0 Micro-B plug into the USB 2.0 Micro-B socket. The convenience of a USB 3.0 Micro-B socket with a USB 2.0 Micro-B plug can be reached for a USB 3.0 Micro-B socket on two components: USB 2.0 and USB 3.0. In the USB 2.0 part, you can easily insert a USB 2.0 Micro-B plug. The USB 3.0 Micro-B plug socket is also structurally split into two parts and can only be inserted into the USB 3.0 Micro-B socket (or USB 3.0 Micro-AB).
The mindset of two houses with cable technologies is thought of only in the same great permissions and TV sets.
- It is also possible to transmit a sound signal to an add-on to a video signal.
- Yakness.
The half-length plug is a chain of roses, which connects to the socket. At Nimechchina є flat and round plugs, which, however, must fit into the nimetsky nests. Be aware of the difference in the whole world, as you do not want to fit into the different countries. A vinatta for such European powers. The fork is used for supplying livelihoods to other annexes through the socket.
- Great Britain Ireland Cyprus Malta.
- Navi podovzhuvachi, such as plugged in to the outlet, pull the plug live.
Usogo in the USB 3.0 Micro-B є ten pins. Outside standard contacts VBUS, D-, D +, GND, SSTX-, SSTX +, GND_DRAIN, SSRX- and SSRX + є one more specific contact ID, features for identifying the OTG mode.
Rose'єm USB 3.0 Micro-AB
Much USB 3.0 Micro-AB will only be installed in outbuildings that accept the OTG (On-The-Go) standard (just like USB 2.0 Micro-AB). The USB 3.0 Micro-AB socket can accept USB 3.0 Micro-B, USB 3.0 Micro-A, USB 2.0 Micro-B and USB 2.0 Micro-A plugs. And the axis of the USB 2.0 Micro-AB nesting roses will be superfluous with the USB 2.0 Micro-B and USB 2.0 Micro-A plug-in roses.
The plug of the power cable is connected to the socket: the plug will be attached, in this rank, I will fit one plug of the power cable, the plug is plugged into the socket, and I will. Roz'єm I will attach a vikorist to see and replace the cable with living in small, sweethearts, great and road outbuildings. For very small, small by-ends attaching a cord, life cannot be seen. Here the cable is installed at the attachment and not connected through the plug to the attachment.
New cables, roses, kolіrne koduvannya
Tsi roses vikoristovuyutsya on the power supply cables of the annexes, which practically do not heat up the robot for an hour. Streaming stream of interconnections maximum 10 amperes. In the capacity of computers and peripheral outbuildings, as well as outbuildings in the audio and video industry and scenic possession.
USB 3.0 Type Cables
The following types of USB cables will be available for the flexibility of USB 3.0 roses:
USB 3.0 Type A (Male) - USB 3.0 Type A (Male)
USB 3.0 Type A (Male) - USB 3.0 Type B (Male)
USB 3.0 Type A (plug) - USB 3.0 Micro-B (plug)
USB 3.0 Micro-A (plug) - USB 3.0 Micro-B (plug);
USB 3.0 Micro-A (Male) - USB 3.0 Type B (Male)
For adaptations that generate warmth and heat, the plugs of hot water and roses are used for a hot drink. Promislovi pilos, portable burners, old waffle lines and lines, as well as new ones with a large living unit. Refrigeration plugs are not suitable for hot or hot attachments!
To that, the fork of the house is like a small fork I will attach. Plugs may not be large, since there is no reason why it stinks to enter the outlet, and, in such a rank, the transmission of data will get lost, if you use a plug from the outlet. To describe the lecture portals, additionally they are often placed at the round bow.
cable, tightly tied from the attachment from one tip and a plug-in USB 3.0 Micro-A plug from the last tip;
cable, hard wiring from attachments from one tip and plug-in USB 3.0 Powered-B from one tip;
a cable that is hard to tie with an attachment, or you have to use a new (non-standard) rose from one tip, and a USB 3.0 type A plug rose from the last tip.
The plugs can be plugged when the telephone cables are connected and the cables are connected to the hedgehog. Tsey interface is used for analogue transmission in a framing sound. In addition to high-end analog telephones and adapters to telephone sockets, cables and roses, it can also be used for facsimile devices and wire modems.
The whole plug is also shaped to fit the telecommunication cable. Ale є kіlka "version" of the tsyy type of z'єdnannya. How does the smell come from? I want it to be unavailable, there is a small number of versions of this type of transmission, which are promoted for the economy and the speed of transmission.
USB (Universal serial Bus- "Universe last bus") - last interface transmission of tribute for medium and low-medium peripheral annexes.For connection, a 4-wire cable is used, with two darts being used for receiving and transmitting money, and 2 darts for living in the peripheral annex. Factory installed in the lines USB live Allowing the connection of peripheral attachments without livelihood.
If I want to be physically identical, the protocol can be seen, especially the plan is confused with one. There are protocols that change the variety of services and their options. Let's be amazed at the characteristics of the cutaneous protocols.
The price of the latest version, the reviews of the price, will be an hour of great standardization. Growth rate up to 4.5 W. The price is mainly for the duplication of these functions and annexes, as in the given hour of establishment. For example, the amount of money will be transferred to 10 Gbit / s, which is a reference to animovanim.
Main types
USB cable stocked from 4 midwives - 2 livelihood guides and 2 livelihood guides, and grounded wraparound (screen).
USB cables May the physical tips "to the attachment" and "to the host". It is possible to implement a USB attachment without a cable with a tip "to the host" inserted into the case. I am able to wake up the cable at the prism(for example, USB keyboard, Web camera, USB Misha)I want a standard fence for outbuildings full and high speed.
USB bus it is strictly ordered, so that the understanding of the "head attachment" (host, USB controller, insert the input into the microcircuit of the bridge mother's pay) that "peripheral attachments".
Attachments can be trimmed with liveness +5 type of shine, ale can and vimagati zovnishnu dzherelo grabbing. A service regime is adopted for attachments and services for the command from the bus from the nobility of the main living for the protection of the service and on the command from the bus.
USB ready"Hotter" plug-in and plug-in attachments... It is possible to create a ground contact for the signaling contact for the provider. When connected rose mu USB chill out grounding contacts, the potential of the buildings of the two outbuildings will grow larger and away from the signaling conductors to overstretch, to move as well as to be attached to the new phases of the three-phase power grid.
on the logical equals add USB I will receive the transaction and transfer of the data. Skin package skin transaction to revenge your number endpoint on the annex. When the driver is connected to the kernel of the OS, I read and add a list of end points and create a structured data for combining with a skin end point. The value of the tip point and structures of the data at the core of the OS is called pipe.
Kintsev points, and hence, і channels, scho lay up to one of 4 classes:
1) streaming (bulk),
2) hard (control),
3) isochronous (isoch),
4) interrupt.
Low-level attachments, such as Misha, you can't mother izochronous and streaming channels.
Keruyuchiy channel indications for exchange with attachments in short packets of power supply. Be-like pristіy m keruyuchiy channel 0, which is permissiveє software security OS read short information about pristіy, including the code of the virobnik and the models that are used for the driver vibration, that is the list of the final points.
Transfer channel Allowing the delivery of short packets and in that, and in the same direction, without attracting them to the confirmation / confirmation, or even with the guarantee of the hour of delivery, the package will not be delivered in less than a few seconds. For example, vikoristovutsya at the add-on (keyboard, mish or joysticks).
Isochronous channel Allowing the delivery of packages without a guarantee of delivery and without confirmation / confirmation, or a guaranteed speed of delivery of N packages per bus period (1 KHz for low and full speed, 8 KHz for high speed). Vikoristovuyutsya for the transmission of audio and video information.
Streaming channel yes, the guarantee of the delivery of the skin package, I will automatically pay for the transfer of the money for the non-required annex (re-upgrade or emptying the buffer), or don’t guarantee the quickness of the delivery. Vikoristovutsya, for example, in printers and scanners.
Shini hour last for a period, for a cob of a period the controller transfers to all tires a package "cob to a period". For a long period of time, packets and transfer are transferred, at the same time, if necessary, in an hour, when they are lost, during the period, keruyue packets are sent to the rest of the streams.
By the active side of the tire If the controller is responsible, the transfer of the package from the annex to the controller is implemented as a short supply of the controller and the information provided by the annex. The distribution of packages for the skin period of the tire can be opened for the sleeping devices of the controller and the software for the driver; Direct access to DMA memory (Direct Memory Access) - the mode of exchanging data between the annexes, or between the annexes and the main memory, without participation Central processor(CPU). As a result, the transmission speed increases, and some data does not overpower the CPU and back.
The size of the package for the end point is sewn up to the end point table with a constant, change is not for the end. The win is vibrated by the attachment rosette from the quiet, which is supported by the USB standard.
Technical characteristics
USB Capacities:
Visoka shvidkist obminu (full-speed signaling bit rate) - 12 Mb / s
- Maximum amount of cable for high speed exchange - 5 m
- Low-speed signaling bit rate - 1.5 Mb / s
- Maximum amount of cable for low speed exchange - 3 m
- Maximum connected annexes (including razmazhuvachi) - 127
- You can connect outbuildings with discounts exchange
- There is no need to install additional elements such as SCSI terminators
- supply voltage for peripheral outbuildings - 5 V
- The maximum rate of living for one prіtіy - 500 mA
Razpayuvannya rose USB 1.1 and 2.0
USB signals are transmitted by two wires of a shielded cable.
Here :
GND- lantsyug "building" for living of peripheral outbuildings
V BUS- + 5V also for lancet living
Tire D + designated for the transmission of tributes
Tire D- receive tribute.
USB 2.0 drawbacks
Want maximum speed transmission Danih USB 2.0 to become 480 Mbit / s (60 Mbyte / s), it is not hard for life to reach such speed (~ 33.5 Mbytes / s is practical). The price is explained by the great tweaks of the USB bus with a power supply for the transfer of data and by the way of transmission. For example, the FireWire bus, I want to lower the bandwidth of 400 Mb / s, less by 80 Mb / s (10 Mb / s), less than USB 2.0, in reality it will allow you to save more throughput capacity Obmіnyuvatsya data from hard disks and іnshim attachments іberіgannya information. At the connection with the cym of flexible mobiles accumulating for a long time already "fit" into the lack of practical throughput USB health 2.0.
