LVDS(低壓差分信號(hào))標(biāo)準(zhǔn)ANSI/TIA /E IA26442A22001廣泛應(yīng)用于許多接口器件和一些ASIC及FPGA中。文中探討了LVDS的特點(diǎn)及其PCB (印制電路板)設(shè)計(jì),糾正了某些錯(cuò)誤認(rèn)識(shí)。應(yīng)用傳輸線理論分析了單線阻抗、雙線阻抗及LVDS差分阻抗計(jì)算方法,給出了計(jì)算單線阻抗和差分阻抗的公式,通過實(shí)際計(jì)算說明了差分阻抗與單線阻抗的區(qū)別,并給出了PCB布線時(shí)的幾點(diǎn)建議。關(guān)鍵詞: LVDS, 阻抗分析, 阻抗計(jì)算, PCB設(shè)計(jì) LVDS (低壓差分信號(hào))是高速、低電壓、低功率、低噪聲通用I/O接口標(biāo)準(zhǔn),其低壓擺幅和差分電流輸出模式使EM I (電磁干擾)大大降低。由于信號(hào)輸出邊緣變化很快,其信號(hào)通路表現(xiàn)為傳輸線特性。因此,在用含有LVDS接口的Xilinx或Altera等公司的FP2GA及其它器件進(jìn)行PCB (印制電路板)設(shè)計(jì)時(shí),超高速PCB設(shè)計(jì)和差分信號(hào)理論就顯得特別重要。

介紹了LVDS 接口的原理和優(yōu)點(diǎn),接口機(jī)的硬件組成以及在設(shè)計(jì)LVDS 接口時(shí)需注意的事項(xiàng)。關(guān)鍵詞 LVDS;數(shù)據(jù)傳輸;時(shí)序 當(dāng)聲吶在海洋中執(zhí)行任務(wù)時(shí),前置預(yù)處理機(jī)設(shè)備接收到的數(shù)據(jù)不僅需要送往數(shù)字信號(hào)處理機(jī)進(jìn)行實(shí)時(shí)分析,還經(jīng)常需要使用數(shù)據(jù)記錄儀將海上各種復(fù)雜的信號(hào)數(shù)據(jù)記錄下來以供事后分析研究;在數(shù)據(jù)分析時(shí)需要將數(shù)據(jù)記錄儀中記錄的數(shù)據(jù)在聲吶設(shè)備上回放出來。由于聲吶設(shè)備記錄的數(shù)據(jù)量大,在實(shí)時(shí)記錄和回放過程中需要很高的數(shù)據(jù)吞吐率,這就要求在前置預(yù)處理機(jī)、數(shù)字信號(hào)處理機(jī)和數(shù)據(jù)記錄儀三者之間建立一個(gè)高速、可靠、有效的傳輸接口。本文的任務(wù)即是要設(shè)計(jì)這樣一個(gè)數(shù)據(jù)傳輸接口,可以將前置預(yù)處理機(jī)的多通道模擬信號(hào)轉(zhuǎn)換為數(shù)字信號(hào),同時(shí)傳輸給數(shù)字信號(hào)處理機(jī)和數(shù)據(jù)記錄儀,也可將數(shù)據(jù)記錄儀回放的數(shù)據(jù)轉(zhuǎn)送數(shù)字信號(hào)處理機(jī)。

This article is based in part on Bob Place s ADO is AOK (a simple ADO tutorial). Wrapper Usage This is consist of 2 classes. CDyndb : This Class manages connections and recordsets. Recordsets are organized as linked list (CList) and you can access them using their ids. CDynRec : This class is the node to populate for each recordsets.
