很多不同的厂家生产各种型号的计算机,它们运行完全不同的操作系统,但TCP.IP协议族允许它们互相进行通信。这一点很让人感到吃惊,因为它的作用已远远超出了起初的设想。T C P / I P起源于6 0年代末美国政府资助的一个分组交换网络研究项目,到9 0年代已发展成为计算机之间最常应用的组网形式。它是一个真正的开放系统, ...
This application note describes a reference system which illustrates how to build an embeddedPowerPC® system using the Xilinx 1-Gigabit Ethernet Media Access Controller processor core.This system has the PLB_Gemac configured to use Scatter/Gather Direct Memory Access andthe Serializer/Deserial ...
Abstract: With industrial/scientific/medical (ISM) band radio frequency (RF) products, often times users are new to the structure of Maxim's low pin-count transmitters andfully integrated superheterodyne receivers. This tutorial provides simple steps that can be taken to get the best performan ...
The super-junction structure, which has P-type pillar layers as shown left,
realizes high withstand voltage and ON-resistance lower than the conventional
theoretical limit of silicon.
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...
