Whats USB flash drive?

What's USB flash drive?
A small, portable flash memory  card that plugs into a computer's USB port and functions as a portable hard drive. USB flash drives

are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive. USB flash drives have less storage capacity than an external hard drive, but they are smaller and more durable because they do not contain any internal moving parts.

USB flash drives also are called thumb drives, jump drives, pen drives, key drives, tokens, or simply USB drives.

Whats HDMI?


What's HDMI?

HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable.



HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless digital audio formats Dolby® TrueHD and DTS-HD Master Audio™ with bandwidth to spare to accommodate future enhancements and requirements.

VGA to RCA Cable - Using Your Television As a Computer Monitor


VGA to RCA Cable - Using Your Television As a Computer Monitor

Switching from VGA to RCA ports is something that you rarely think about doing, but sometimes the need to do so does present itself. With all kinds of different connection devices available from VGA toHDMI to RCA and so on, you never know which you will need next. You can easily use a converter to go from VGA to RCA if the need arises.

 
What isVGA?
The first thing you are probably wondering is what the difference is between the two. With so many types of technology, it can be a real chore to determine what type of connection is which. VGA, or video graphics array, is a type of plug that carries signals from things like gaming consoles to computer monitors. The plug itself connects to the monitor through three rows with five small pins in each row, and then is secured by a small screw on either side of the plug's head.

 
What is RCA?
RCA connections are easily recognized by the red, yellow and white plugs they feature. They originated in the 1940s and were named for their creators at the Radio Corporation of America, or RCA. While RCA cables are some of the most commonly used connection devices for TVs, speakers, game systems and other audio visual equipment, they do offer some drawbacks. While they are an affordable method for setting up your entertainment systems, the number of cords and wires required can quickly create a large mess around your television system.

 
Converters
VGA to RCA connection can easily be made with special cables or cords that merge the two types of plugs with ease. These types of cords are reasonably priced and readily available online and at any store with an electronics section. They can be used to connect a number of devices to each other that otherwise would not be compatible with each other. For example, you can use them to connect a projector to a television, or a game system with television cables to a computer monitor.

 
The creation of VGA to RCA adapters, and other cables of similar nature has allowed technology to evolve over time without leaving it's predecessors completely behind in the dark. With new plug types constantly evolving for new types of machines, these sorts of conversion cords allow you to combine old and new technology for your entertainment needs with minimal effort.

 
Regardless of whether or not you know the difference between HDMI, RCA and VGA cables, you can rest assured that you will eventually need some sort of adapter cable to setup your entertainment system or your computer. If you pride yourself on your entertainment setup then you may find it advantageous when adding new pieces to your system to keep a few different converters on hand, like a VGA to RCA cable.

 
VGA to RCA cables can be used for many different things. Most people familiar with them would probably mention using your computer on your TV screen, but it can work the other way around too. You can hook up DVD players, game systems, or even audio/visual systems to a monitor with the right converter.

USB Flash Drive - From USB 1.0 to USB 3.0


USB Flash Drive - From USB 1.0 to USB 3.0

There were just a few people who could imagine how USB Flash drives will settle in our lives when they firstly appeared. The technology was and is evolving rapidly. USB port version 1.0 was introduced in 1996 and was quickly followed by version 1.1 in 1998. As IT customers' demand increases, it became apparent that the performance specifications of the port were inefficient. However, this changed in April 2000. We can sedately consider this moment as the beginning of the USB flash drive era as the USB 2.0 port was introduced. It greatly exceeds his predecessor in every way. The maximum transfer rate of USB 2.0 is 480 Mbits/s which is 40 times faster then USB 1.1.



Companies have come to the great opportunity and to thrive on developing Flash drives. With maximum read/write speed of nearly 40 Mbytes/s it seemed like an endless variety of USB memory sticks kept coming to the IT market.

                                                                                        

Even so, nobody thought of it as a replacement for a floppy disk, but here we are in 2010 and floppy drives are no longer required since USB flash drives have overtaken all its functionality from booting (system rescue), through data storage, backup and transfer, to function as an installation medium. USB drive is much more durable, secure and has larger capacity reaching 256 GB which is over 150,000 times more compared to 1.44 MB floppy disk.



Year 2010 brought us another innovative step in USB technology: USB 3.0 - the most powerful USB port to date with an amazing maximum transfer rate of 3,200 Mbits/s. USB 3.0 flash drives were already introduced; ranging from 16 GB to 256 GB and covering the field of security, reliability and speed.



We already have USB flash drives with very useful features like the whole operating system on-the-go or special USB flash drives designed to store important personal medical records which may save your life one day and a lot more. Although it might seem like nothing else can be done to improve the USB technology, immense progress from the 1998 is a testimony to continued innovative efforts in further advancing and enhancing of the USB flash drives.



The future of USB 3.0 looks very promising and everyday thousands people are working hard on developing new ways of using USB memory sticks. Let's see what the future brings us.

USB3.0 technology standard



Speaking of Removable storage drive,everyone is familiar with it,USB flash drive ,removable drive ,etc..Most of them adopt USB2.0 interface,and the theoretical read and write speed is just 480Mb/s,which could not satisfied the consumers demand with the growing volume documents of game ,high definition movies and so on.At this moment,the appearance of eSATA interface seems to has solved this problem.however,eSATA interface solved the speed,there is another problem,that’s power supply.As eSATA interface has no power cord so that consumers will feel unconvenient when use it.In such a context,a new technology standard emerged,it is USB3.0.



USB3.0 downward compatible with standard,and with both easy to use and plug&play .The goal is to introduce a product that connect level is more than 10 times faster than current ones and adopt the same architecture with wired USB. USB3.0 port and cable could achieve backward compatibility and support the future optical transmission in addition to optimize the USB3.0 specification to achieve lower power consumption and higher protocol efficiency.Its speed is faster than sSATA and no necessary to supply power separately,and could instead of sSATA port.



Many manufactures launched their own USB3.0 products from the end of 2009,and now we could buy removable disk and flask disk with USB3.0 port.Meanwhile,with the apperance of AMD 8 motherboards series,more and more motherboards could support the USB3.0 port,and we believe that USB3.0 technology standard will be populared soon.

The rise of copper price react on the development of connector industry


The rise of copper price react on the development of connector industry

Fluctuations in copper price has seriously affected the development of connector industry.Recently,the copper price increased so fast that also affected its manufacture and R&D.
 
As we know, connector is made of four parts: contacts,insulation,shell and accessories,and the hardcore is the contacts.
 
Contacts are the key components for connector to complete the electrical connection, which is composed of Male and Female contact that through mating to complete the electrical connection.And the Male contact is made of Brass,Phosphor bronze.
 
There have 2%~8% Tin and 0.1%~0.4 phosphor in Phosphor bronze,and the left parts is Copper alloy,Brass is a kind of alloy that made of Copper and Zinc,the important metal for both of which are Copper.So the increasing of copper price affected the manufacture of connector.
 
Relevant market data shows that the demand of copper in the first half year increased so fast ,a increase of more than 20% compare to the same period of last year.
 
At present,the target price wll be reduced to US$5750,and if the market is stable,price can be rebound to US$7000, Fluctuations in copper price is among ¥46500~55000 within 3 months,which has reacted on the development of connetor industry.

The present condition of DVI connector


The present condition of DVI connector

Current DVI connectors are 18+1,24+1 and 18+5,24+5 four designs.



18 pin is Single channel DVI, the transfer rating is half of 24pin ones,that’s 165MHz. The resolution of Single channel DVI could support is the same with Dual channel ones on picture plane display.However, refresh rating is just half of 24 pin DVI ,which will reduce the display quality.Generally speaking,the largest refresh rating of Single channel DVI interface just could support to 1920*1080*60hz or 1600*1200*60hz, that means current 23-inch widescreen monitor and 20-inch normal monitor,if larger ,the display quality will be reduced.And the 24 pin Dual channel DVI is necessary for large screen LCD。

 
As to 18+5 and 24+5 connector are belong to DVI, the extra 4 pin is used for compatible with the traditional VGA analog signal.This connector is always used in graphics card ,not in monitors except single channel ones like 970P.



If the monitors is less than 23-inch widescreen or 20-inch of normal,the 18 pin DVI could play its role normal.Besides, a graphic card with dual channel output is very important if you want to use a large screen monitor.So now most of graphic cards adopt the DVI-I Dual channel interface ,which characteristics could come up to the requets.Actually, DVI could achieve the proper performance in many graphic cards.

The Latest HDMI Standard


The Latest HDMI Standard

Getting a 3D cinema experience isn't new, but films such as Avatar have shown how the latest technology has added greatly to the realism of the effect, even if we still have to wear those 3D glasses for now! But the real benefit will come in being able to have that 3D experience on the TV in our home. The larger flatscreen, high-definition TVs already give us a picture size and quality closer to the cinema experience, but adding that third dimension demands quite a leap in the underlying technology, and fundamental to the success of HDTV and 3DTV is the High-Definition Multimedia Interface (HDMI).

 
In the past, we could rely on good quality SCART, coaxial, phono and digital optical cables to deliver the audio and video signals to, and between, the various components in our entertainment system - the decoder, TV, hi-fi etc. These cables moved signals that were mostly analogue or single source digital, but the coming of digital HDTV changed all that. Not just the high definition picture but multi-channel digital surround sound now dictated that the bandwidth requirements became extremely high. It presented a terrific opportunity but also a severe test for the manufacturers of the players and TVs, and not least for the suppliers of cables, connectors and switching devices. Any signal losses down the line would become critical since digital signals don't degrade gracefully, as with analogue - in simple terms, the picture doesn't just go a little fuzzy, it breaks up big time! The requirement was for a high quality, high bandwidth, single cable solution to transmitting these digital signals.

 
HDMI was pioneered by Silicon Image but is now developed by a group of the leading electronics manufacturers. HDMI provides a very high-speed digital signal transmission medium capable of transmitting signals at up to 5Mbps (5,000,000 bits per second), but even the first versions of HDMI didn't have 3D TV in mind. That was added with the development of the HDMI 1.4 specification (the latest version at time of writing), which also includes integrated data connectivity as manufacturers aim to stay one step ahead of the trend towards the fully-wired digital home.

 
The two major advantages of a digital signal over analogue are no signal compression and no digital-to-analogue signal conversion. When any one of these two take place, some degree of signal loss is unavoidable and so keeping things in the digital domain is the first important step. But even a digital signal can become imperfect. HDMI is a standard that provides the basis for fast, high-bandwidth digital signal transmission, but as with most technologies, how that standard is applied will result in quality differences between brands and individual products.

 
There are many factors that pose problems to a signal being transmitted through any cable, be it analogue or digital. However, due to the high transmission speeds of a digital signal, it is even more delicate and easily affected than analogue. Since the core technology of HDMI relies on TMDS (Time Minimized Differential Signaling) - a way to transmit huge amounts of data over a twisted pair - impedance (resistance) and interaction between the twisted pairs plays a more significant role in the performance of the cable than ever. I spoke with Joe Carri of UK-based specialist cable developer IXOS and he explained some of the key points in designing an HDMI cable. In order to produce a cable that will not alter the timing of the digital signals, IXOS engineers its cables with PC-OFC (High Grade Pure Crystal Oxygen-Free Copper), a copper with fewer impurities than standard Oxygen-Free Copper, thus creating less resistance. Triple layer shielding also minimizes both radio frequency (RF) and electromagnetic (EM) interference from both internal and external forces. IXOS also applies lower than industry standard percentages for allowable tolerances on engineering and manufacturing imperfections, and there's no cost-cutting on the connector used, which in the case of IXOS are designs approved by Silicon Image.

 
One of the most testing issues caused by the extremely high bandwidth requirement of HDTV and 3DTV is the effect on cable length. Manufacturing a cable to pass 720p/1080i is relatively straightforward for a specialist manufacturer and IXOS have cable lengths of up to 20m that give no noticeable difference in the picture quality, but with twice the resolution, 1080p demands that twice as much information needs to get through. In the case of IXOS, every HDMI cable will pass 1080p up to 7.5m (almost 25 feet), and this is verified at the factory by testing every single cable using a standardised Eye Diagram Test. This test analyzes the quality of a digital signal at the far end of the line by showing a repetitively sampled oscilloscope measurement that gives a clear visual depiction of the signal's behaviour at it passes through the cable.

 
The speed at which the industry has moved on from 720p/1080i has been rapid, and what was originally hailed as "high definition" was quite quickly surpassed by the 1080p resolution of the movie-making industry. Manufacturers in the consumer electronics market all had to up their game. Some were ahead of the curve, some a little behind. Those ahead of the curve use research and development to help them recognise potential problems that would hinder further performance improvements. IXOS's Joe Carri highlighted FEXT (Far End Cross Talk) as one example. FEXT has been a common problem with the HDMI connector. Because of the connector's small size and multiple solder points, exposing the contacts without insulation within a very tight area, the impedance of the cables is altered at the point of contact. When the impedance of a cable changes, crosstalk will occur between two or more wires of different impedances and this can significantly reduce the quality of the picture and sound. Minimising FEXT by stabilizing the impedance at the solder points is therefore extremely important, and the company's patented solution was incorporated at a very early stage in the development of their own HDMI cables.

The fast development of connector market lead manufacturers to launch new products

With the development of electronic devices with higher transfer speed and smaller style,connectors also follow the trend to face the competition among thousands of domestic connector manufacturer,who need to have advantage in manufacture capability ,special service and customer support.
 
There is no reason to doubt that cable assemblies will be affected by wireless technology obviously,the quantity of sales within the next 5 years will reduce at least 25%,that’s mean less connector plug demands.Wireless application will also affect the following connector types:
A: RJ45 plug (current quantity of annual sales is more than 1 billion pcs )-will be affected by 802.11 wilreless LAN competition.
B: USB plug and socket(current quantity of annual sales is more than 2 billion pcs)-will be affected by WUSB competition.
C: RCA connector-(current quantity of annual sales is more than 1 billion pcs)-will be affacted by bluetooth.
 
The development of connector technology with high-speed transfer is also progressed under high-speed trend of civilian products,communication,computer and measure machines. The demand of digital interaface connector used in LED TV,DVD player,STB is increasing,which industry absorb lots of manufacturers stay in mechanery industry to join ,the competition of new products is increasing.
 
Molex also launched two SMD type right angle FPC connector for mobile phone,digital camera and other small application.It said that 0.50mm pitch of 501461 series FPC connector is with the appearance of only 0.80mm high and 3.20mm deep,which is called the shortest and smallest connector among all of current types.
 
At the same time,TYCO also launched a new economic round waterproof connector,which could meet the trend of smaller and fashion appearance for LED light market and suit for the outdoor connection application for various LED lights,such as LED light bar,LED spotlighting,LED washing wall landscape lighting,LED advertising board lighting,LED tunnel lighting,LED public lighting and so on.

The connector development prospect


The connector development prospect

The deveopment of 3G telecommunication network, fusion of 3 kinds of networks and some government measures like automotive consumer subsidies, all of which indicate that connectors in China market will develop so fast in the next few years. Electronic manufacturers from other countries are migrating to China market, which will become a production center of electronic products.As a big consumer country for electronic components, although it was effected by financial crisis in 2009,the sales of connectors are increasing stably.

In recent years,suppliers of connectors and cable components followed their customers and have came to China so that strengthened t he manufacture capability of chinese connector and cable components.Now there are more than 600 manufacturers in mainland,including 37.5% of TW manufacturers ,14.1% of Europe ones.But foreign brands still hold the top technology in high-end connectors,such as MOLEX,AMP ,etc.What Our connector companies produce are mainly labor-intensive products,such as cables,terminals,mirco switch,power line,etc., they need to improve their competition in technology.

 
Although connectors are not the protagonist in devices,they are costars.If IC is the heart of devices,connectors and cables will be the hands and feet,which play animportant role in devices.

The demand of connector products will be very large,connector companies should improve their technology to adapt the market so as to put them at an advantage.

Something about DVI connector and related connectors


Something about DVI connector and related connectors

DVI (Digital Visual Interface) was developed by the industry body DDWG (the Data Display Working Group) to send digital information from a computer to a digital display, such as a flat-panel LCD monitor.
 
DVI uses TMDS (transition minimized differential signaling) to transmit large amounts of digital data from the source to the display, resulting in a high-quality image. DVI technology successfully moved from the computer marketplace to the audio/video realm, and is now found on many high-end TVs, DVD players, and HDTV set-top boxes.
 
DVI took a step forward withHDMI, which integrates audio and video into a more compact interface. The DVI interface uses a connector that resembles a DB-style connection. However, instead of round pins, the DVI connector uses flattened pins that appear "twisted" at an angle. This design is referred to as an LFH (low force helix) connector. The peculiar shape of the pins ensures a good contact with the mating connector. DVI connectors use thumbscrews for retention.
 
Most DVI connectors have 24 pins and a single larger, offset ground bar. These are called DVI-D interfaces, and carry a digital signal only. Some DVI connectors, called DVI-I, have four extra pins that surround the offset ground bar. A DVI-I interface is designed to carry both digital and analog signals.

Whats USB flash drive?


What's USB flash drive?

A small, portable flash memory  card that plugs into a computer's USB port and functions as a portable hard drive. USB flash drives

are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive. USB flash drives have less storage capacity than an external hard drive, but they are smaller and more durable because they do not contain any internal moving parts.



USB flash drives also are called thumb drives, jump drives, pen drives, key drives, tokens, or simply USB drives.

Whats HDMI?


What's HDMI?

HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable.



HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless digital audio formats Dolby® TrueHD and DTS-HD Master Audio™ with bandwidth to spare to accommodate future enhancements and requirements.

Setting Up HDMI With A Long Cable


Setting Up HDMI With A Long Cable

HDMI is currently the best choice for Audio and Video connections. Because it transfers both audio and video on one cable, in an uncompressed format, it's perfect for high definition displays and setups. HDMI is also compatible with the latest digital transmission standards like HDCP (High-bandwidth Digital Content Protection).



HDMI has one main drawback. Unfortunately it is not designed for long cable runs. The higher the resolution and the longer the cable, the more the signal has a chance of become degraded. This is because the cables are manufactured using twisted copper pairs of very small-gauge wire. Unlike normal coaxial cable, this makes interference and degradation a reality whenever dealing with lengths over 50 feet.



Fortunately, the wise creators of the HDMI standard thought long and hard about their specification. Because they choose to include a line for power within the cable, it has become possible to power repeaters that are internal to the cable. Normally, signal boosters and repeaters need an external power source to boost the signal, but because of it's design, HDMI can actually be extended without an external power source.



These types of HDMI repeaters come in several varieties. There are cables with repeaters built in, as well as plug in repeaters that will connect two HDMI cables together while actively repeating the signal. A converter can also be used to change the HDMI signal into a signal that will travel over standard Cat5 cable. With this type of system, a unit is placed at either end of the cable run to transform the signal to go over cat5, and then transform it back to HDMI on the other end.



If extra care is needed for your signal, external power can also be used for your HDMI repeater. This is a good idea because many HDMI sources simply don't output the power needed to do a good job of repeating the signal. Even cables with built-in repeaters often allow for an external power supply to be attached. This is just a little extra protection for your signal and may be a good idea depending on the situation in which the repeater is needed.



Since HDMI is a digital signal, it cannot be degraded much before the picture and audio is not longer decipherable. On analog signals, you can get quite a bit of degradation before the picture is totally gone. On digital signals, corrupt is corrupt, you will start to see major artifacts with only a little bit of signal degradation.



This is why it's important to use a proper repeater for all your long cable runs. Do your research and find out which extender option is best for you: built-in, standalone repeater, or cat5 HDMI extender. No matter what the situation is, there is probably a solution that will work for you.

Present problems and challenges of domestic automotive connectors


Present problems and challenges of domestic automotive connectors

 In recent years,the market scale of domestic automotive connectors have more than 3 billion yuan,shiments of which has came up to 80 million pcs,is 8%~10% of all the connector industry market.But this percentage is lower than 15%-the average percentage of worldly connectors in automotive connector application industry.As low economic base and backward technology,domestic connector manufactures have lagged behind the foreign-funded enterprises. 

 
Existing problems of domestic automotive connectors are as follows:
a: Few professional automotive connector manufacturers and small scalel with different product performances.
b: The service awareness and market awareness of automotive connector manufacturers is relatively weak,and need to be strengthened.
c: Lack of participation in whole design,their own connectors have no intellectual property right.

 
There are about 50 manufacturers who devote to automotive connector production.But except foreign-funded enterprises,our home manufacturers are not professional and the scale is small,quality of products could not compare with world famous brands.

 
At present,compare to foreign companies,low technoloy level and quality of home connectors are objective facts.But meanwhile, we also worry about their weak service and market awareness. Most of dometstic finished cars appear as foreign equipments that lead our connector manufacturers hardly to participation in finished car and cable designs&development ,seldom communication with finished car manufactures so that domestic connector factories hardly to get intellectual property right.

 
Besides,the reason of foreign-funded enterprises have great competitive is: domestic companies are not as strong as foreign-funded ones from not only technology but also economy.

 
The future of domestic automotive connector industry will be a competitive market between foreign companies and home enterprises.And China will become one of the most important manufacture country with the development of foreign companies and home enterprises.
