5 Gsps高速數據采集系統的設計與實現

以某高速實時頻譜儀為應用背景，論述了5 Gsps采樣率的高速數據采集系統的構成和設計要點，著重分析了采集系統的關鍵部分高速ADC（analog to digital，模數轉換器）的設計、系統采樣時鐘設計、模數混合信號完整性設計、電磁兼容性設計和基于總線和接口標準（PCI Express）的數據傳輸和處理軟件設計。在實現了系統硬件的基礎上，采用Xilinx公司ISE軟件的在線邏輯分析儀（ChipScope Pro）測試了ADC和采樣時鐘的性能，實測表明整體指標達到設計要求。給出上位機對采集數據進行處理的結果，表明系統實現了數據的實時采集存儲功能。

pci e PCB設計規范

This document provides practical, common guidelines for incorporating PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on both baseboard and add-in card PCB designs. This includes interconnects between PCI Express devices located on the same baseboard (chip-to-chip routing) and interconnects between a PCI Express device located “down” on the baseboard and a device located “up” on an add-in card attached through a connector. This document is intended to cover all major components of the physical interconnect including design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge-finger and connector considerations. The intent of the guidelines and examples is to help ensure that good high-speed signal design practices are used and that the timing/jitter and loss/attenuation budgets can also be met from end-to-end across the PCI Express interconnect. However, while general physical guidelines and suggestions are given, they may not necessarily guarantee adequate performance of the interconnect for all layouts and implementations. Therefore, designers should consider modeling and simulation of the interconnect in order to ensure compliance to all applicable specifications. The document is composed of two main sections. The first section provides an overview of general topology and interconnect guidelines. The second section concentrates on physical layout constraints where bulleted items at the beginning of a topic highlight important constraints, while the narrative that follows offers additional insight.
