【应用】AR0521P1LV、AR1511D3、AR1811D3、AR2411D3汽车ADAS数字高清摄像头ESD保护
近年来智能汽车越来越成为主流，ADAS高级驾驶辅助系统更是成为智能汽车的必备选项，随着越来越多的数字高清摄像头被集成到车上，车载系统的数据传输量越来越大，而且对图像质量要求也越来越高。目前常见的ADAS数字高清摄像头有:前置摄像头，后置摄像头，侧置摄像头，电子后视镜CMS，AVM 360°环景摄像头等。
尽管视频数据在汽车领域的使用和重要性与日俱增，但仍然缺少全球公认的标准来定义视频数据在车辆共享的方式。汽车厂商将自行选择自己偏好的解决方案，其中包括专有标准，例如APIX、GSML和FPD-Link，分别支持6GB/秒、10GB/秒和13.3GB/秒速度。此外速度高达1GB/秒的汽车千兆以太网(1000BASE-T1)的使用也与日俱增。
汽车视频数据专有标准
a、APIX-汽车像素链路
汽车像素链路(APIX)由Inova Semiconductors设计，并于2008年由 Fujitsu授予许可。它可用于在长达15m的距离内传输数字视频信号。第三代APIX3已于2016年发布，数据速率最高达到6GB/秒。
b、GMSL-千兆多媒体串行链路
GMSL 是Maxim Integrated专有的SerDes接口，主要用于摄像头应用。第三代GMSL将数据速率提高至10GB/秒以上，还可支持PoC。
c、FPD-Link-平板显示器链路
FPD-link最初是为视频显示而设计的，但将摄像头连接到ADAS计算单元也很常见。如今，FPD-link由TI拥有，在汽车ADAS应用中非常受欢迎。FPD-Link 支持通个单个链路实现高达13.3GB/秒的数据速率和双向通信。此外，FPD-LinkII允许在单端链路中使用同轴电缆和PoC。APPLIED POWER AR0521P1LVAR1511D3,AR1811D3AR2411D
摄像头视频链路的ESD要求
上文介绍的三种视频链路接口对外部保护有相似的要求。在选择合适的ESD保护器件时，应该重点关注两个主要参数:ESD电压等级和信号完整性。下面我们将对这两个参数进行论述。
为了实现±15kV或更高的ESD电压等级，并在实际应用中构建非常稳健的系统，必须采用先进的ESD保护技术。如图1所示，ESD保护器件有两个可能位置:ESD1和ESD2。要达到最佳ESD保护性能，建议的位置是ESD1，这样就会直接在远离敏感的PHY和电路的连接器处钳住ESD脉冲。
通常，在汽车测试中，还要为视频链路执行“电池短路”测试。在这种情况下，要求ESD1保护器件的关态电压(VRWM)高于13.5V。如果不执行电池短路测试，则可以选择5V或更低的VRWM。
由于在电路中电容具有"隔直"作用，因此ESD2位置不受电池短路测试的影响。在这种情况下，ESD2可以使用5V或更低的关态电压(VRWM)。某些情况下，需要有带屏蔽层电缆的电容耦合，可看作是ESD保护器件的可能接地参考。
当今汽车视频链路的数据速率日益加快，新一代视频链路已经达到了13.3Gbps的高数据速率，今后还可能提高到16Gbps。在此类场景下，对于设计工程师而言，信号完整性(SI)扮演着非常关键的角色。正常工作过程中，ESD保护器件两端的电压非常小，差分视频电压通常低于1V。在这种情况下，ESD保护器件等效为一个小电容，并联在信号传输路径上。对于信号完整性而言，ESD器件结电容Cj是最重要的参数之一。由于数据速率高达16GB/秒因此必须达到小于1pF的超低Cj值，这一点非常关键。结电容Cj对散射参数S21的影响如图2所示，最高频率6GHz。
在6GHz的频率下，低于1.0pF的电容值的曲线在-3dB极限值上方，0.5pF的电容值的曲线甚至在-1dB上方。因此，在最高6GHz的频率下，低于1pF甚至低于0.5pF的电容值都允许很好的信号传输。
另外，封装及其对信号线路布线的影响，可能对信号完整性产生很大影响。一般来说最佳选择是紧凑型无引脚封装，例如DFN(Dual Flat No-lead package双侧扁平无引脚封装)，与有引脚封装相比，它的寄生效应比较小。此外，它们通常具有很小的管脚尺寸，对信号线路的布线产生的影响很小，因而对PCB线路阻抗的影响也非常小。
结论
现代汽车系统对数字高清摄像头、信息娱乐和安全性的需求急剧增长，因而我们需要非常先进的高速ESD解决方案，可以通过EMC合规性测试，并在实际应用中保持稳健可靠。 ESD可能导致出现故障，甚至导致对系统的不可逆破坏，这正是汽车厂商会花费大量成本召回产品的原因所在。ESD保护器件是避免这些故障、保持系统高度稳健可靠所必需的。
APM应能微针对数字高清摄像头设计提供的ESD器件，兼具低电容和高ESD鲁棒性优势。结电容Cj可选03pF-1.0pF，器件可承受高达8A(8/20μs)的浪涌电流，和±20kVESD脉冲电压，采用非常紧凑的DFN1006-2或SOD-323封装。
