A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM Express® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI Express and Serial ATA on the other hand.

Abstract: Engineers often wish that radio susceptibility (RS) or radio immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from radio frequency interference.

Multioutput monolithic regulators are easy to use and fi tinto spaces where multichip solutions cannot. Nevertheless,the popularity of multioutput regulators is temperedby a lack of options for input voltages above 30V andsupport of high output currents. The LT3692A fi lls thisgap with a dual monolithic regulator that operates frominputs up to 36V. It also includes a number of channeloptimization features that allow the LT3692A’s per-channelperformance to rival that of multichip solutions.

In addition, qualified HSPICE Integrator Program members have access to HSPICE integrator application programming interfaces (APIs). Collaboration between HSPICE Integrator Program members will enable customers to achieve more thorough design verification in a shorter period of time from the improvements offered by inter-company EDA design solutions.

The correct answer for each test bank question is highlighted in bold. Test bank questions are based on the end-of-chapter questions. If a student studies the end-of-chapter questions (which are linked to the italicized words in each chapter), then they will be successful on the test bank questions.

資料說明介紹 PCB Translator_CAMCAD轉(zhuǎn)換器3.95版本，里面含CAMCAD_3.9.5a_crack文件，可以對(duì)軟件進(jìn)行破解 （需要安裝PCB Translator后才能進(jìn)行破解） 針對(duì)PCB設(shè)計(jì)文件的RSI轉(zhuǎn)換器能夠轉(zhuǎn)換PCB設(shè)計(jì)和生產(chǎn)所需要的所有信息。它們包括：庫(kù)，布置位置，插入屬性信息，網(wǎng)表，走線，文字和銅箔，以及其它相關(guān)的項(xiàng)目。不需要執(zhí)行"導(dǎo)入Gerber"和"交叉參考"就可以完成所有這些工作。事實(shí)上，根本不需要定義參考，因?yàn)檐浖梢詮脑嘉募袷街刑崛〕鯟AD數(shù)據(jù)，并把它直接輸出到新的文件格式中。只需要注意CAD系統(tǒng)本身的限制就可以了。 CAMCAD PCB 轉(zhuǎn)換器 CAMCAD PCB 轉(zhuǎn)換器是一個(gè)功能完善的PCB CAD 轉(zhuǎn)換器，圖形用戶界面也很淺顯易懂。CAMCAD PCB 轉(zhuǎn)換器支持大多數(shù)流行的CAD格式，比如Cadence Allegro, Orcad, Mentor and Accel EDA,也支持工業(yè)標(biāo)準(zhǔn)格式，比如GenCAM, GenCAD, and IPC-D-356.CAMCAD PCB 轉(zhuǎn)換器允許導(dǎo)入CAD文件到CAMCAD圖形用戶環(huán)境中，校驗(yàn)數(shù)據(jù)，修改數(shù)據(jù)，然后可以把數(shù)據(jù)導(dǎo)出為任意格式的文件。這些特性意味著用戶可以完全控制所有的事情，比如層的轉(zhuǎn)換，也能解決CAD格式之間不兼容的問題。 一個(gè)案例,如果要轉(zhuǎn)換Cadence Allegro文件到PADS,所有必須的設(shè)計(jì)信息都會(huì)包含在新的文件中。不過，Cadence Allegro允許板子上的銅箔重疊，PADS卻不允許。Allegro 文件可以正常導(dǎo)入到CAMCAD。如果要立即把這個(gè)文件導(dǎo)出到PADS，程序會(huì)有錯(cuò)誤提示。這時(shí)，可以使用CAMCAD的數(shù)據(jù)處理特性來改變有問題的銅箔，解決問題后再導(dǎo)出到PADS。 下面的矩陣表格，列出了CAMCAD PCB 轉(zhuǎn)換器所支持的當(dāng)前PCB的轉(zhuǎn)換組合。Import Modules 一列中列出了可以被導(dǎo)入（讀取）的所有ECAD文件格式。Export Modules一行中列出了可以被導(dǎo)出（寫）的文件格式。在這個(gè)矩陣中的任意輸入和輸出模塊組合轉(zhuǎn)換都是可行的。當(dāng)然，沒有任何ECAD到ECAD的轉(zhuǎn)換器是絕對(duì)完美的。由于ECAD layout系統(tǒng)有自己獨(dú)特的特性，而這些可能不能直接轉(zhuǎn)換到另一個(gè)有自己獨(dú)特特性的ECAD系統(tǒng)中。 CAMCAD PCB 轉(zhuǎn)換器支持的組合 建議配置：Windows 2000 或者 XP Professional，800 MHZ 處理器，512MB RAM 17"顯示器，1024×768分辨率 Copyright 2004 Router Solutions Incorporated RSI Reserves the right to make changes to its specifications and products without prior notice.
