Electronics Information

Following Samsung, Sony, sharp announce high profile after the transition to a high-end LED LCD TVs, as the technology matures, continental LED LCD TV is also carried out to promote flows, in mid-August, Hisense 47-inch LED LCD TV it fell to Yuan. Skyworth, KONKA, TCL said in “11” before the full range of LED LCD TVs, manufacturers are optimistic about 11 gold selling point.

Compared with traditional LCD TVs, LED LCD TV color and image more expressive power, low power consumption, long life, more safety and environmental protection, its appearance is more lightweight. Due to the excellent characteristics of the LED light source, TV using this technology can enhance the color of a field’s value, make LCD TVs at a lower power consumption to achieve a higher level of brightness and color saturation, and animation performance. For the LCD TV business, which is currently a rare area of new high-end products.

LED TV to promote the reason behind the slow

From May to August, the LED LCD TV listing for 3 months, the domestic market did not see better. According to the household appliance industry market research firm owell consultation of statistical data, in 2009 about domestic LED LCD TV sales in the tens of thousands of traditional LCD TV sales of 11 million units. Store marketing staff complained about the poor LED LCD TV sales are due to high prices.

Samsung 46-inch LED LCD TV prices in more than 21,000 yuan, using edge RGB-LED backlight mode Sony 40-inch LED TV price reach 26,999 Yuan, equivalent to three with the size of ordinary LCD TV price. Hisense, Skyworth 55 inch LED LCD TV price 16,000 yuan, cost about 8,900 a traditional LCD TVs of the same size.

LED LCD TV prices higher because of its high cost of LCD module light source. LED TV backlight was used by light-emitting diodes, this more expensive than ordinary LCD TV light source. Large size LED LCD TVs, backlight can be accounted for to the module cost about 40%, and module costs 70% per cent of total cost of the television. Tsinghua tongfang Wang Xiangdong, Deputy General Manager of the consumer electronics division have said in public in late July, LED backlight involves a number of patented technology, enables TV manufacturers to pay high royalties, led LED LCD TV prices drop down.

China electronic Chamber of Commerce Deputy Secretary General Lu Renbo believes that “it requires a certain amount of time”. LED TV price appears this situation main is LED products is is universal early, due to LED TV products scale smaller, in production cost Shang relative traditional LCD TV has is large of gap, while in performance Shang than traditional LCD TV has mass of upgrade, now LED TV also is “has powerful technology strength enterprise launched of, and representative future development direction of products”, overall,, price/performance also is reasonable of interval.

Businesses looking forward to day store

In 2009, however, had become a LED LCD TV clear import period. Foreign TV brands announced their plans in the Chinese LED LCD TV. Jin Rongxia, President of Samsung Electronics in the greater China area marketing made it clear that, 2009 Samsung Electronics aims LED LCD TV in TV sales reached 10% per cent. Sharp data is similar.

Before national day, domestic TV makers will also launch waves of LED LCD TV promotion. Skyworth Zhong Zhifeng, General Manager of Guangzhou Branch introduction, the company will be “11” before and after the launch of 42-inch to 55 inch full range of LED LCD TV product. “We extend primarily to small and medium size. “KONKA head of marketing said, the company will be introduced in the national day new LED LCD TV, and LED two series of promotional projects have been completed at the end, when the KONKA 26 inch to 52-inch LED LCD TV product line. At present, the LED LCD TV is primarily large size.

Market practitioners believe that day is the traditional TV season, home-made color TV manufacturers choose national collective racing LED TV, are expected to promote good results. LED LCD TV is TV the next big thing for development, will become the new alternative to traditional LCD TV LED TV products. Seen from a TV total cost of use, to well below the LCD and LED TV CRT TV. In a similarly ordinary LCD TV and Samsung 40-inch LED TV comparison of launch in 2009, and to turn 5 hours a day, each year Samsung LED TV can help consumers save power consumption of 40%, 10 years, saving electricity costs to consumers enough to buy a LCD television.

According to the Office of the China electronic Chamber of consumer electronics survey research data show that consumer LED TV product concern has now reached 75%, the Chinese market this year consumers as much as 34% to buy LED TV. China electronic Chamber of Commerce Deputy Secretary General Lu Renbo believes that LED TV become the mainstream market trend and the trend of the times will be coming soon, it is expected that by 2011 more than ordinary LCD TV LED TV market share will be.

WHAT ARE THE BENEFITS OF ELECTRONIC COMMERCE
Customer care has benefited from various in e-commerce, EC also e-business continue to pay dividends as long as the benefits as reported by e-commerce site.wordpress.com (nd) are still achievable. Reduction in cycle time, staff empowerment and cutomer support are just a few of the benefits. Efraim Turban et al (2008).

CYCLE TIME
The cycle time for an organization refers to the time it takes to complete a transaction; also turn around time, speed of operation etc Internet banking is one of the ways Nigerian banks increase customers satisfaction and cycle time. More transactions are done on the internet, ATMs, POS machines, through patnerships with card companies like MasterCard, Interswitch, VisaCard and the rest of them. It is easy to find all these in almost all Nigerian banks now because the management wants to minimize cost while maximizing profit. Trading equities used to take a very long time before orders can be successfully effected before but can now be done by just one click on the right button in the right website. The same is applicable for purchasing University of Liverpool recommended textbooks. Inputting my mastercard details makes the process of search and final purchase shorter and easy to accomplish for me. EC has brought to the world the likes of ebay, amazon.com and others responsible for online auction. Time is money, so instead of driving all about looking for a shop that stocks what I need to buy, I would rather go to the internet search for it and purchase it immediately.

EMPLOYEE EMPOWERMENT
Organizations now allow their staff to take certain steps that were not possible without electronic commerce. Booking of Consumer loans used to be on paper before in Oceanic Bank until recently when the bank designed an online procedure that empowers staff to issue more loans per hour. The reason for this is not far fetched; a soft copy consumer loan file needs little or no correction since the already inputted formulas are there to do the correction. Checking the consumer loan can now be done at a very high speed because there are software for testing if the excel file followed the desired procedures or not. With the bank empowering their staff in EC, more value is added because staff now sees themselves as important participants of the bank as well.

Electronic Commerce makes it simple for online tutors to detect malpractices amongst students unlike in offline Universities, where Doctors and Professors have to read the hard copy assignments submitted by various students, there will always be cases where collution and plagiarism will not be detected. Students will surely copy themselves knowing fully well that the instructor might not get to know. This is not the case in an EC committed University where all assignments are submitted online through software like Turnitin and safe assign.

FACILITATE CUSTOMER SUPPORT
Customer support was taken to another level through highly specialized customer relationship management; Norton allayed fears that my monthly internet bill is exorbitant. It all started when my hard drive crashed and I lost a recently purchased Norton antivirus. I was frustrated and had to chat online with customer care representative of Norton through their chat software. As if that was not enough, the agent I spoke with blew my mind when he told me that he was going to install the software into my laptop from his remote location. I thought to myself this must be a joke until I saw my mouse moving and clicking certain menus on my desktop. It was a wonder then, I thought I was looking at a Norton miracle, he put my laptop in order within five minutes and still told me thank you. I replied as many times as possible and fell in love with purchasing my antivirus solutions from Norton because I feel that their EC investments have paid off after all.

CONCLUSION
Every good idea has to develop through changes, the world never stayed in one place. What might be perfect today might be faulty tomorrow, no wonder Polaroid felt comfortable until the digital imaging swept their business away. Holycoast.com (nd) It is very correct to say that EC has come to change the world and it is doing just that real well and fast too. The value of improvement that has met the organizations cannot be overemphasized and thus will continue to draw the attention of other corporations to invest in new ideas, innovations and technologies.

Introduction

With a market size estimated at more than $650M and more than 1.4B crystal oscillators supplied annually, quartz crystal oscillators have long been the preferred choice for clock generation in consumer, computing, and communication applications. Quartz oscillators are available in a wide
range of frequencies, package sizes, and stabilities. In addition to providing excellent jitter performance, quartz oscillators are available from a broad range of suppliers.

Quartz Resonator Based Oscillators

Crystal oscillators require a unique quartz resonator for each frequency. The crystal oscillator assembly process requires the quartz to be cut, x-rayed, lapped, mounted, and sealed into the
final package . Fabrication of these resonators becomes increasingly difficult at frequencies over 100 MHz because the resonator must be manufactured to very tight tolerances. The complexity of the manufacturing process is subject to poor yield at multiple steps within the
process forcing material restarts and overall production delays.

In addition to lead times, reliability is a chief concern with quartz oscillators. Quartz oscillators are susceptible to contamination which can affect both the center frequency and the ability of the XO to start up reliably. If an oscillator fails in the end application, often the entire system fails because the oscillator provides critical timing for the electronics.

MEMS Resonator Based Oscillators

The industry has long been searching for a technology that enables the replacement of quartz oscillators with a solution that addresses lead time and reliability concerns while providing performance on par with quartz oscillators. Over the last several years, micro-electromechanical
system (MEMS)-based oscillators have emerged as a possible replacement technology for quartz oscillators. MEMS-based oscillators provide an alternative solution to quartz by replacing the
quartz oscillator with a CMOS-based mechanical resonator.

Si500 Silicon Oscillator

Silicon Labs Si500 silicon oscillator leverages a standard IC manufacturing flow. The silicon oscillator is fabricated using standard submicron CMOS technology and standard low-cost
plastic packaging that does not require a hermetic seal. The silicon oscillator is factoryprogrammed at test to a specific frequency, signal format, and supply voltage.

Si500 Technology Overview

The heart of the architecture is a low phase noise, frequency flexible LC oscillator. Using innovative mixed-signal analog circuitry, the oscillator is compensated for frequency variation due to operating temperature range, aging, initial frequency accuracy, supply voltage change, and output load
change. The silicon oscillator supports a wide frequency range, generating any output clock frequency from 0.9 to 200 MHz. Selection of the frequency, output type, supply voltage, and output enable (OE) is stored in non-volatile memory (NVM). At power-on, the Si500 performs a
self-calibration using these stored parameters and configures itself for operation.

Temperature Stability

Temperature stability refers to how much the oscillator frequency varies over the operating temperature range of the device. For the Si500 silicon oscillator, tight temperature stability is achieved through dynamic temperature compensation. The device has an on-board temperature
sensor that, upon detection of a temperature change, dynamically adjusts the frequency of oscillation of the LC oscillator to maintain a stable output frequency.

Aging

All oscillators experience drift in the frequency over long periods of time. The effect is called aging and is an important specification in the overall frequency stability budget. Aging behavior is dependent on several aging mechanisms including the design of the resonator, the assembly of the oscillator, the contamination level surrounding the resonator, the design of the electronics, and the operating temperature. To determine an upper bound on aging performance, it is
necessary to control as many of the mechanisms as possible and to verify conformance through extensive aging studies.

Reliability

Quartz oscillators require hermetic packaging for the crystal. Package leaks or internal contamination can lead to long term frequency aging, or if severe enough, can even prevent oscillation. Consequently, oscillator manufacturers minimize contamination by using costly, hermetically sealed ceramic or metal packaging and special processing. Done properly, reliable operation can be achieved, but package and assembly costs will be considerably higher than with non-quartz CMOS only devices. Being a mechanical device, MEMS resonators are susceptible to the same contamination issues and also require hermeticity.

Shock and Vibration

Shock and vibration can also limit the reliability of quartz-based oscillators. Quartz crystals are mounted above the oscillation electronics using epoxy or metal clips supported on one side only. Attaching the crystal on one side places the crystals center of gravity far away from
the support point allowing the crystal to swing like a diving board when exposed to vibration.

Jitter Performance

Period jitter is a key specification for oscillators since it impacts the setup/hold time, noise margin, or bit-error rate of systems that require alignment between clock and data. Period jitter describes how much any period may deviate from the ideal clock period and is used to determine the setup/hold time margin within a digital system. The amount of margin required depends greatly on the how many timing violations (i.e., bit-errors) a system can handle. In most designs, no timing
violations are allowed over the lifetime of the product, so the amount of margin is quite large. Period jitter is related to phase noise[2] and is often dominated by phase noise at far offset frequencies up to half of the clock frequency.

Programmable Output Buffer

Because the Si500 can generate frequencies across a large range (0.9 to 200 MHz), the output buffer design must provide easy connectivity for the many common receiver formats and voltages used in this range. The Si500 employs a programmable output buffer with support for both
differential and single-ended formats while easing the design effort by incorporating common external components.

Conclusion

With advances in mixed-signal CMOS technologies, silicon oscillators like the Si500 are now competitive with oscillators that use traditional quartz or MEMS resonators. By eliminating the need for these mechanical resonators, the Si500 offers significantly improved reliability when
shock, vibration, and oscillator start up are considered. In addition, the Si500s simplified manufacturing flow reduces cost and enables short predictable lead times when compared to traditional quartz based oscillators.
