HD-FIFO is a proprietary design technology used to overcome issues commonly hindering and limiting other frame buffer devices (e.g. SDRAM, DDR…etc) found in FPGA solutions. Traditional FPGA implementations require higher I/O pin totals and place heavy demands on logic resources and property memory controllers, forcing a designer to move up to higher grade FPGAs. In contrast, AverLogic's HD-FIFO requires significantly less in I/O pins and logic resources, at the same time overcoming latency issues therein. The programmable I/O controls and double buffer mode increase design flexibility and reduce FPGA overhead.

* Standard LQFP 128-pin package
HD Quad Splitter for Coaxial SDI and HDMI – Great advantages for the Broadcast Display, Digital Signage or Surveillance Industry
HD cameras and related equipment for video applications will unquestionably alter this market segment landscape. HD video will significantly improve surveillance clarity in poor visual conditions, providing great advantages, such as improved zoom capabilities, license plate recognition, facial recognition and motion detection, especially at far distances or in dimly lit areas. In fact, we have already seen many HD surveillance cameras enter the market, including 720p (1280x720) models. But more recently, HD solutions with 960H (960x576 or 960x480) have improved SD (Standard Video) resolution by up to 30% and have laid the foundation for coaxial cabling as the medium of choice, which has also been sanctioned by the HDcctv coalition.
The Coaxial cabling for Digital Signage or Surveillance applications is a logical choice. The cable can carry an uncompressed video without traffic congestion, video lag or frame loss – this is advantageous for a real-time HD cameras deployment. In addition, many video system installations have pre-existing coaxial cabling for their standard definition video cameras – in effect, converting to HD video would only entail camera replacement without re-cabling.
AverLogic proposes an HD Quad Video Splitter for Coaxial SDI solution using an advanced HD Video FIFO design, featuring AverLogic's AL460 HD FIFO IC chip, arguably, one of the fastest HD data buffering solutions in the market today. Applications
