【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
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。

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。

【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。

【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
