21ic News Arrow Electronics, Altera Corporation and NewKen Technology Inc. announced that they have provided the industry's first full HD WDR 3G-SDI all-inclusive solution for users in China and Taiwan through Arrow Electronics. This all-inclusive solution was jointly developed by Arrow Electronics and NewKen and supported by Arrow Electronics, including Altera Cyclone® IV FPGAs and CPLD security chips, supporting Apical's HD WDR Full Image Signal Processing (ISP) pipeline IP and AltaSens' 1080p60 A3372E3-4T image sensor, this sensor provides very high quality images. This is conducive to the design of inexperienced engineers to complete the video surveillance camera design project quickly and efficiently.

The biggest problem encountered in designing surveillance cameras is system integration. With this all-inclusive solution, the R&D team avoided system integration issues such as heat sink and system noise. Moreover, Arrow and NewKen offer a flexible business model that includes ODM, complete modules and one-time open source code to meet the needs of different users.
The current reference design on the market is based on standard CMOS image sensors, limited by the inability to support low brightness to direct sunlight wide brightness level variation, resulting in a black target or all white. The full HD WDR 3G-SDI all-inclusive solution solves this problem based on the WDR CMOS image sensor. Due to the large amount of data generated by these image sensors (20 bits x 1.2 Mpixels per color, 60 frames per second) in the Image Sensor Pipeline (ISP), the amount of data is too large to achieve on-chip processing. Altera Cyclone IV FPGAs can handle large computational algorithms that convert raw image data into the standard digital output needed to produce crisp video images.
Erhaan Shaikh, vice president and general manager of Altera Asia Pacific, said: "We are very pleased to provide users with a high-performance and easy-to-use all-inclusive surveillance camera solution. With this solution, the system company has accelerated its approach to the market while passing Delivering valuable features to end users and highlighting product advantages. Altera Cyclone IV Series FPGAs offer low cost, low power and high performance in surveillance camera applications, and are extremely flexible. In addition, Altera, Arrow Electronics and NewKen Technologies is committed to providing exceptional support and service to help them succeed."
Lin Jianzhong, Vice President, Semiconductor Markets, Asia Pacific, said: "We are pleased to partner with Altera to develop this all-HD WDR 3G-SDI turnkey solution. Altera offers the industry's best field-programmable gate array (FPGA) technology This all-inclusive solution combines Altera Cyclone® IV E FPGAs and CPLDs
The security chip supports Apical's HD WDR Full Image Signal Processing (ISP) Pipeline IP and AltaSens' 1080p60 A3372E3-4T image sensor. Combined with Altera's industry's first HD WDR video surveillance chipset, Arrow Electronics offers complete turnkey solutions, technical support, professional supply chain management, and a full-package solution module that supports models to help manufacturers accelerate The market introduces a smarter, more cost-effective next-generation video surveillance camera system. â€
Paul Chen, General Manager of NewKen Technologies, Inc. commented: "As far as we know, there are currently no ASIC chips on the market that fully meet the WDR Full HD ISP camera specification. To complete the WDR 3G-SDI camera project, not only is it very professional. System engineering experience, but also to obtain the support and resources of the chip supplier. NewKen uses the design flexibility of FPGA to realize the function of WDR, and combines the basic results of its own 3G-SDI to design a full-featured WDR with reasonable price for the industry. 3G-SDI camera solution. With Altera's comprehensive design resources and technical support from Arrow Electronics, we decided to use Altera's FPGAs in the solution. In addition, the three companies jointly provided a comprehensive development platform to reduce development costs and risks. To make this product available to the market quickly and to get a wider range of applications."
Supply information
Now, Arrow Electronics provides full HD WDR 3G-SDI all-inclusive solutions to users in China and Taiwan.
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.
