【选型】车载激光雷达千兆以太网防护选2极GDT气体放电管UN1812-150CSMD四通道TVS阵列SP2555NUTG

技术问答

为满足车载激光雷达高速数据传输的需求，一般通过FPGA→超高速千兆以太网芯片→以太网变压器→RJ45网口路径通过网线连接至外部电脑做数据实时调试使用，因RJ45接口裸露在外面，设计时必须做共模4kV，差模0.5kV防雷保护设计。一般是在以太网变压器初级侧用2极GDT气体放电管做共模防护，在以太网变压器次级侧用TVS管做差模防护，典型应用电路参考如下图1所示。

图1：千兆以太网雷电浪涌防护设计示意图

千兆以太网共模4kV抗雷击绝缘是用1.2/50μs标准雷电波模拟测试得到，对应到8/20μs雷电波测试为2kA，推荐硕凯电子的2极贴片GDT气体放电管 UN1812-150CSMD，1812贴片封装，通流量2kA，标准的直流击穿电压150V±20%（120V~180V），典型电性参数参考如下图2所示。

图2：硕凯电子GDT气体放电管UN1812-150CSMD典型电性参数

千兆以太网0.5kV差模防护部分，推荐选择四通道集成的TVS阵列更符合设计需求，既可以吸收以太网变压器后级的差模能量，又可以起到静电防护的功能，考虑到激光雷达因PCB板空间有限对小型化设计要求非常高，不建议采用图1中的4颗分立TVS管方案，推荐选择LITTELFUSE（力特）四通道TVS阵列SP2555NUTG，典型应用电路参考如下图3所示。

图3：LITTELFUSE四通道TVS阵列SP2555NUTG用于千兆以太网防雷保护示意图

LITTELFUSE的四通道TVS阵列SP2555NUTG，是一款低电容瞬态抑制二极管阵列，I/O电容低至2.5pF，可为高速差分数据线路提供针对ESD（静电放电）、CDE（电缆放电）、EFT（电气快速瞬变）以及雷击感应浪涌保护，采用µDFN-10封装，反向工作电压2.5V，每个器件均可保护多达 4个信道或2个差分线对，最高电流可达45A（IEC第61000 4- 5 2版），最高电压可达30kV ESD（IEC 61000-4-2），典型电性参数参考如下图4所示。

图4：LITTELFUSE四通道TVS阵列SP2555NUTG典型电性参数

最后，总结下推荐LITTELFUSE四通道TVS阵列SP2555NUTG理由：

1、每个输入/输出电容低至2.5pF，有助于维护信号完整性，并最大限度地减少数据丢失，同时提供免受电气威胁的更强大设备。

2、3.0mm x 2.0mm μDFN封装经过优化，可在高达45A和30kV ESD的条件下保护两个差分数据线对（四个通道），单机用2颗，可以大幅度节省PCB板空间，有利于产品小型化设计需求。

3、走线采用“直通型”设计结构，可保障信号完整性、减少电压过冲并简化印刷电路板设计。

4、市场上有成熟的应用设计，产品性能可靠。

【经验】为PC电脑DVI 接口选择一款合适的ESD防护器件SP3004-04XTG

因PC电脑的DVI接口是外置在PC电脑外面，非常容易被静电ESD打到，为同时兼顾有效保护和高频讯号传输的完整性及线性度，必须在DVI接口和DVI接收芯片组间加入ESD保护器件，本文推荐一款Littelfuse推出的汽车级、超低容值的SP3003系列四通道双向TVS阵列，型号为SP3003-04XTG

【成功案例】提升USB3.0的布线设计质量秘诀：四通道二极管阵列SP1004U-ULC-04UTG

笔者曾经设计的一款车载域控制器采用了USB3.0模块，在初始设计阶段使用的是TE Connectivity的单通道TVS产品PESD0603-240对USB3.0接口进行ESD防护，经过评估分析，改为采用Littelfuse推出的四通道二极管阵列SP1004U-ULC-04UTG，此举能减小USB3.0接口布线占用的PCB面积、改善ESD性能，并能减小物料和制造成本，可谓一举三得。
