NS SDXILEVK用于Xilinx Spartan-3A三速SDI和视频时钟方案
Triple-rate SDI & video clocking daughter card for Xilinx Spartan-3A/3E FPGAs National Semiconductor in collaboration with Avnet and Xilinx developed a triple-rate SDI and video clocking daughter card for the Xilinx Spartan-3A/3E development kits. The daughter card plugs directly into the Spartan development board through an EXP connector. The combined solution of the daughter card and the development kit provides broadcast video system designers a comprehensive platform for rapid evaluation and prototyping of new designs to reduce time to market.
