DDS-232光电隔离器用户说明书
隔离232方案选择
（1）传统方法，使用光耦TLP521
注意：VCC为5V电源，是由变压器的另一组绕线整流、滤波、稳压产生+5V。
使用光耦6N137
（2）使用ADuM公司的信号隔离芯片ADUM1201
采用ADUM1201实现3.3V控制系统与5V供电的RS-232收发器的隔离通信
注意：需要一个+5V隔离电源，可以由DCDC产生，也可由变压器的另一组绕线整流、滤波、稳压产生+5V。
（3）使用ADuM公司的带DCDC信号隔离芯片ADUM5241
其内部集成一个5V-5V的内部DC/DC隔离电源，当VDD1输入一个5V的外接电源时，VISO会输出一个+5V/10mA的电压。
可以为后端的RS-232收发器供电；但当前端输入3.3V电压的时候，内部DC/DC隔离电源则不工作，后端的VISO需另外接电源供电。
（3）使用ADuM公司的带232隔离芯片ADuM3251
图中采用三极管加上拉电阻升压的方法将 3.3V的输入信号拉升到5V，输入到ADuM3251E的Tin引脚，而ADuM3251E的Rout引脚5V输出信号经电阻分压，转换成3.3V 信号输入到以3.3V电源工作的控制器中。
需要注意的是，上拉电阻及限流电阻都会不通程度的影响数据传输速率。
ADuM3251E外围共需6个电容，2个瓷片104电容，和4个电荷泵电容，泵电容是很重要的，用来稳定RS-232的输出信号，保证足够的升压，因此推荐使用耐压16V，0.1uF 的电解电容。

bufferseparated by a silicon oxide (SiO 2)insulation ed in conjunction with isolated power supplies,these devices block high voltage,isolate grounds,and prevent noise currents on a data bus or othercircuits from entering the local ground and interfering with or damaging sensitive circuitry.A binary input signal is conditioned,translated to a balanced signal,and then differentiated by thecapacitive isolation barrier.Across the isolation barrier,a differential comparator receives the logictransition information,then sets or resets a flip-flop and the output circuit accordingly.A periodic update pulse is sent across the barrier to ensure the proper dc level of the output.If this dc-refresh pulse is not received for more than 4m s,the input is assumed to be unpowered or not functional,and the failsafecircuit drives the output to a logic-high state.For ISO7420F and ISO7421F,the failsafe circuit drives the output to a logic-low state.CAUTIONNote that although these devices provide galvanic isolation of up to 4000V,thisEVM cannot be used for isolation voltage testing.It is designed for theexamination of device operating parameters only and will be damaged if highvoltage (>5.5V)is applied anywhere in the circuit.1.2Functional Configuration of the Dual-Channel Digital IsolatorThe pin-outs of the dual-channel digital isolators are displayed in Figure 1.The EVM comes with anISO7421installed;however,the user may reconfigure the EVM for use with any of the footprints.Figure 1.The ISO7x20x and ISO7x21x PinoutsThe ISO7220A,ISO7220B,ISO7220C,ISO7221A,ISO7221B and ISO7221C have TTL input thresholds and an input noise filter that prevents transient pulses of up to 2ns in duration from being passed to the output of the device.The ISO7220M and ISO7221M have a CMOS Vcc/2input threshold,but do not have the noise filter and the additional propagation delay.2Dual-Channel Digital Isolator EVM SLLU098C–June 2007–Revised December 2010Submit Documentation FeedbackV

CAN-3202 智能型 CAN 总线光电全隔离两路中继器 说明书
产品简介：CAN-3202智能型CAN总线光电全隔离两路中继器，硬件采用高速微处理器设计，软件采用高效优化的算法，中继采用存储转发缓冲机制，使本产品吞吐量高达每秒3000帧时能保证绝不丢包。
CAN-3202是CAN-2202的智能版，其最大的优点是能使用在两边不同速率的CAN总线网络中。
CAN (Controller Area Network)是一种串行总线系统，特别适合组建智能工业设备网络和楼宇自动化控制系统。
CAN拥有高传输速度(高达1Mbps) 和高可靠性，能以高性能和高品质的方式实现高度可靠的监控系统，同时CAN具有的出错自动重发功能大大提高了通信的可靠性，而灵活多变的CAN特有的识别码机制，能极大地满足用户的协议要求。
因此，CAN系统首先被大量地应用于汽车网络中。
基于CAN网络的实时和多主机特性，它可以很容易地帮助你建立冗余系统。
CAN-3202有两种模式：设置模式和工作模式。
在设置模式下，用户可对它的参数进行设置。
而在工作模式中，它完成上述的中继转换。
CAN-3202特别适合大流量多结点的CAN总线数据传输应用，使用本产品后，能大大突破原来的CAN传输距离极限与节点数量的限制。
CAN-3202采用表面安装工艺，板上自带光电隔离模块，在控制电路和CAN电路之间实现完全电气隔离。
CAN-3202也采用防雷设计，每线提供600W的抗雷击承受力，加上独立的DC/DC电源，这样的三保险设计使CAN-3202具有很强的抗干扰能力，大大提高了系统在恶劣环境中使用的可靠性。
CAN-3202带有DIN-35安装卡座，使用方便，能灵活地在DIN导轨上卡上取下，另外CAN-3202体积小巧，也是便携式系统用户的最佳选择。
