AUDIO & VIDEO ELECTRONICS Robust and low-cost ‘plug-and-play’ digital signage system Powered by the fanless FitPC3 computer running WireSpring’s FireCast EasyStart software, the FitSignage from andersDX offers quick, easy and affordable digital signage for small numbers of screens, ranging from point-of-sale advertising and digital menu boards to tradeshow signs and public safety information displays. This combination of industrial grade hardware with no moving parts and features such as auto power resume, together with easy-touse software, enables signage systems designed for 24/7 unattended use to be set up, mounted behind a display and loaded with content in a matter of minutes, and with energy consumption as low as 10W. Supporting almost all commonly used file types for videos, pictures, news updates, web pages and live TV content, FitSignage uses simple drag-and-drop tools that allow screens to be split into zones offering different content for either viewing only or for touch interaction. Built-in templates eliminate the need for graphics skills, while pre-loaded images and stock animations, ticker tapes and RSS live feeds can be used to quickly create a professional and compelling look and feel. FitSignage is offered in 2 variations, supporting either single or dual display support, with one low, single, lifetime cost and with no recurring maintenance or upgrades costs.

With its small size it enables sharp, pixel-perfect heads-up displays (HUD) in cars. Compared to existing solutions, the MAX3601 excels through brighter light and lower cost. The MAX3601 drives three RGB lasers to provide a brighter light without compromising the low power. The high intensity of the lasers project brighter, more vivid images onto the HUD to alert the driver while enhancing safety. In addition, its high integration means longer battery life, less heat build-up, and a smaller module size. Since the three laser LED drivers are combined into one single IC, the high integration of the device helps to minimize the PCB area in the cramped space behind the dashboard. No separate optics is required. With its low bias power of only 80mW and less than 1W total module power, the chip achieves excellent power efficiency and helps designers to keep heat dissipation and thermal sinking low. The chip is available in 3x3.5 mm, 42-bump WLP and 5x5mm, 40-pin TQFN packages. It is specified over the -40 °C to +105°C temperature range. Maxim Integrated Products www.maximintegrated.com Octal 12-bit ADC uses less than 80mW per channel for medical imaging Texas Instruments has introduced an octal, 12bit, 100-MSPS analog-to-digital converter (ADC) that provides the lowest power consumption in its class for imaging and medical applications. The ADS5295 uses less than 80 mW per channel, which diminishes board heat and power dissipation in higherchannel density applications. It incorporates TI’s digital processing block, which combines commonly used digital functions to help improve signal-tonoise ratio (SNR) and filter harmonics while reducing output data rate for narrow-band applications. The ADS5295 can be used in phase-array architecture systems with higher channel counts, such as ultrasound, security x-ray and non-destructive testing (NDT) applications. Using only 80 mW-per-channel at 100 MSPS and eight channels, it enables designers to increase channel count without increasing power dissipation high-density applications, while still achieving a low noise of 71 decibel full scale (dBFS) SNR. The integrated digital processing block integrates commonly used digital functions, such as a low-frequency noise suppression mode, digital filtering options and programmable mapping of low-voltage differential signaling (LVDS) output pins. This lowers FPGA cost and simplifies LVDS output routing, reducing the number of printed circuit board (PCB) layers and bill of materials cost. The device also outputs data over one or two wires of LVDS pins per channel, reducing the number of interface lines. This creates a two-wire interface, which keeps the serial data rate low to further reduce FPGA cost. An evaluation module (EVM) is available to test the ADS5295 under a variety of conditions. The ADS5295 is available in an 80-pin HTQFP package. Texas Instruments www.ti.com Advanced video annotation controller board The eVAC2000 from Advanced Micro Peripherals (AMP) is a real time NTSC/PAL video overlay and video annotation controller for the PCI/104 systems. Advanced features include a high resolution graphics accelerator, digital NTSC/PAL TV decoder, digital NTSC/ PAL TV encoder and video overlay controller, all contained within a single PC104 card. Accepting up to four composite NTSC or PAL analog video inputs including video cameras, digital video recording equipment or regular TV broadcasts, the eVAC2000 is ideal for a wide range of applications which require titles, dynamic grids or visible watermarking. The high throughput, low latency eVAC2000 uses a high performance 64bit 2D graphics accelerator combined with an 8Mbytes frame buffer to deliver rapid video graphics processing. The board could be used for multi-media displays, live video annotation or medical and industrial imaging.
