【应用笔记】FPGA高速PCB设计指南(Guidelines for Designing High-Speed FPGA PCBs) 在过去5年中，真正模拟CMOS进程的发展已经导致在数字领域中的高速模拟器件的使用。 Over the past five years, the development of true analog CMOS processes has led to the use of high-speed analog devices in the digital arena. System speeds of 150 MHz and higher have become common for digital logic. Systems that were considered high end and high speed a few years ago are now cheaply and easily implemented. However, this integration of fast system speeds brings with it the challenges of analog system design to a digital world. This document is a guideline for printed circuit board (PCB) layouts and designs associated with high-speed systems.
