Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.

The weak local semiconductor equipment companies are once again surprising.
"First Financial Daily" was informed that at the Semicon (Global Semiconductor Materials and Equipment Exhibition) held in Japan last week, Shanghai Zhongwei Semiconductor Corporation (hereinafter referred to as "Zhongwei") announced that its independent research and development for 65 nanometers to 45 nanometer high-end chip production equipment, officially entered the world's top semiconductor mainstream equipment
According to industry insiders, China Micro may have entered the TSMC and SMIC international procurement system. The two international giants have been actively promoting the local production of equipment and components. Among them, TSMC's goal is that the proportion of localized production of equipment will increase to 50% in 2009. SMIC has already adopted local equipment such as China Zhongkexin and Northern Microelectronics in Beijing and Tianjin.
This is also the background of the national “Eleventh Five-Year Plan†to list semiconductor equipment as a key development strategy. Ding Wenwu, deputy director of the Ministry of Information Industry, told this newspaper that during the "11th Five-Year Plan" period, China will strive to be completely autonomous on the 6-inch line equipment, and the 8-inch line lithography machine will be practical, 12-inch line 65-nanometer light. Equipment such as engraving machine has made a breakthrough.
Micron introduced an etching machine and a high-pressure thermal chemical deposition machine. This is the first time that Chinese semiconductor equipment companies have introduced equipment for the above process. Yin Zhiwei, chairman and CEO of China Micro, said that the cost of the semiconductor industry has become one of the keys to determining the success of chip manufacturing companies. The global semiconductor market is continuing to shift towards consumer electronics. Consumers' sensitivity to terminal prices has made upstream chip companies feel unprecedented pressure, which has created opportunities for China Micro.
Yin Zhisheng revealed that at present, two types of equipment have been officially shipped to famous semiconductor manufacturing companies.
Gartner, an international IT research organization, said that Asia's future will become the center of global semiconductor manufacturing and the hotspot of semiconductor equipment production, because 66% of semiconductor devices and 75% of equipment are sold here.
The reason for the rise of China Micro is its team and the capital behind it. Yin Zhiyi has previously served as the global vice president of Intel Semiconductor Technology Executives and Equipment Leading American Applied Materials, specializing in high-end technology research and development. In the mouth of international investors, China Micro has become a local “application materialâ€. Behind it, the names of internationally renowned venture capitals such as Walden International, Goldman Sachs, Lightspeed, Red Dot and American Keyian are shining.
However, what is embarrassing is that although local enterprises such as China Micro has made significant breakthroughs, the equipment industry is still the slowest development in China's semiconductor industry relative to other links in the industry chain.
