This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer desktop motherboard. The material covered can be broken into three main categories: Board design guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per second on an actual motherboard. Section 7 contains a design checklist that lists each design recommendation described in this document. High speed USB OPERATION is described in the USB 2.0 Specification (http://www.usb.org/developers/docs.html).

A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment, AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by changing the coding method,parameters of building blocks,and OPERATION distance.Finally,some simulation results are presented in this paper.

郵件系統(tǒng)是Linux網(wǎng)絡(luò)應(yīng)用的重要組成，一個(gè)完整的郵件系統(tǒng)包括三個(gè)部分：底層操作系統(tǒng)（Linux OPERATION），郵件傳送代理（Mail Transport Agent，MTA），郵件分發(fā)代理（Mail Delivery Agent，MDA），郵件用戶代理（Mail User Agent，MUA）。 Postfix是一個(gè)非常優(yōu)秀的MTA，她素以高效、安全的特點(diǎn)而著稱。Postfix是作者在UNIX上所見過(guò)的MTA中在反垃圾郵件（Anti- Spam或Anti-UCE）方面做得最好的一個(gè)，甚至有很多公司在Postfix代碼的基礎(chǔ)上進(jìn)行二次開發(fā)而推出反垃圾郵件網(wǎng)關(guān)產(chǎn)品。MTA的反垃圾郵件功能，實(shí)際上就是在MTA處理過(guò)程中對(duì)會(huì)話進(jìn)行過(guò)濾。這個(gè)過(guò)濾不但過(guò)濾了發(fā)往自身的垃圾郵件，而且還防止了自身被惡意利用發(fā)送垃圾郵件。Postfix 實(shí)現(xiàn)了目前所有主要的MTA過(guò)濾技術(shù)。postfix是Wietse Venema在IBM的GPL協(xié)議之下開發(fā)的MTA（郵件傳輸代理）軟件。和Sendmail相比Postfix更快、更容易管理、更靈活、更安全。

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system OPERATION to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

ST7529液晶驅(qū)動(dòng) The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write OPERATION with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
