教程资料 为您的FPGA选择合适的电源
Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/tracking and the voltage ripple limits. This application n ...
教程资料 HDB3编解码器设计
HDB3(High Density Bipolar三阶高密度双极性)码是在AMI码的基础上改进的一种双极性归零码，它除具有AMI码功率谱中无直流分量，可进行差错自检等优点外，还克服了AMI码当信息中出现连“0”码时定时提取困难的缺点，而且HDB3码频谱能量主要集中在基波频率以下，占用频带较窄，是ITU-TG.703推荐的PCM基群、二次群和 ...
教程资料 Create a 1-Wire Master with Xilinx PicoBlaze
Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wir ...
教程资料 《器件封装用户向导》赛灵思产品封装资料
Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor devices. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the device. Feature sizes a ...
教程资料 AN522: Implementing Bus LVDS
This application note describes how to implement the Bus LVDS (BLVDS) interface in the supported Altera ® device families for high-performance multipoint applications. This application note also shows the performance analysis of a multipoint application with the Cyclone III BLVDS example.
