【应用】音特可提供具有高可靠性的USB 3.0标准防护方案,采用小型化设计,符合IEC61000-4-2要求
USB 3.0是最新的USB规范,也被认为是SuperSpeedUSB-为那些与PC或音频/高频设备相连接的各种设备提供了一个标准接口。只是个硬件设备,计算机内只有安装USB3.0相关的硬件设备后才可以使用USB3.0相关的功能!从键盘到高吞吐量磁盘驱动器,各种器件都能够采用这种低成本接口进行平稳运行的即插即用连接,用户基本不用花太多心思在上面。新的USB 3.0在保持与USB 2.0的兼容性的同时,还提供了下面的几项增强功能:
极大提高了带宽-高达5Gbps全双工(USB2.0则为480Mbps半双工)
实现了更好的电源管理
能够使主机为器件提供更多的功率,从而实现USB-充电电池、LED照明和迷你风扇等应用。
能够使主机更快地识别器件
新的协议使得数据处理的效率更高
1、建议标准保护方案
1、使用yint的ESD0524P和ESDSR05同样符合IEC61000-4-2的要求。
说明:ESD0524P提供的DFN 2510设计,此设计的优点是倒装工艺,集约化,引脚的寄生电感和电容均比较小,对于高速传输,性号的失真性比对小,焊接结构具有高可靠性,低残压的特点,性价比高。
ESDSR05是采用SOT-143封装,它的1脚PAD设计采用宽接地模式,有效泄放静电或浪涌,从而有效保护小型化LDO或DC,特别给于集成化的USB3.0转换芯片良好的保护。
2、建议参考电路及Layout
3、高性能共模滤波器:
