NS SDALTEVK用于Altera Cyclone III三速SDI和视频时钟方案

作者：时间：2009-11-18 13:24 来源：

NS公司的SDALTEVK是三速SDI和视频时钟子板卡,专门用于Altera Cyclone III FPGA的开发套件.SDALTEVK子板卡通过高速子板连接器(HSMC)直接插到Cyclone III开发板, 为广播视频系统设计师提供了完整平台,能块速评估和出设计原型,从而降低产品面市时间.本文介绍了SDALTEVK子板卡的主要特性和优势, SDALTEVK和Altera Cyclone III主开发板的连接框图以及SDALTEVK子板卡的电路图与材料清单(BOM).

Triple-rate SDI & video clocking daughter card for Altera Cyclone III FPGAs National Semiconductor in collaboration with Altera has developed a triple-rate SDI and video clocking daughter card for the Altera Cyclone III FPGA development kit (sold separately by Altera). The daughter card plugs directly into the Cyclone III development board through a High-Speed Mezzanine Connector (HSMC). The combined solution of the daughter card provides broadcast video system designers a comprehensive platform for rapid evaluation and prototyping of new designs to reduce time to market.

The SDALTEVK kit consists of:
