【技术大神】如何实现USB接口更远距离传输设计？
USB接口由于技术发展时间长，技术成熟得到广泛应用。但传输速率高、频率高，导致它传输距离受限，通常最远传输5米，每加一级USB-HUB，可以延长5米，最多能加5级USB-HUB，表1是USB传输速度和距离对照表。
表1：USB传输速度和距离对照表
USB视频采集卡，就是数据卡将DV摄像机、录像机、播放机中的视频内容采集到电脑中进行制作、剪切，图1为USB视频采集卡的系统框图。视频采集卡与主机电脑通过USB传输，这个距离通常有几十米到一百多米的距离。根据上面表中的传输距离来看，是很难实现的，就算通过5级USB-HUB，也难满足要求，并且USB会产生数据信号的衰减。
图1：USB视频采集卡的系统框图
面对上述的问题，我们对各种传输进行了调研，例如USB-HUB，USB-RJ45，USB-Fiber等方案进行了比较，分别对传输距离、成本进行了比对，表2为各种传输方案的比较表。
表2：各种传输方案的比较表
USB-RJ45理论上可以传输100米，但实际上传输50米以内效果更好。而从表2可知，USB-Fiber方案是目前效果最好的。对于USB-Fiber方案，里面主要包括光模块、传输光纤等成本。根据目前项目100-200米的需求，选择了FIRECOMMS的EDL301T以太网光纤收发器作为传输模块。此模块成本低、体积小，采用650nm光纤，相对来说光纤的价格也低，各方面综合考虑，此方案是最优选择。
在实际的电路设计中，需将USB2.0信号通过专用芯片转换成lvpecl信号，用于驱动光模块。因此对光模块的设计应为通用设计，在USB两端增加EDL301T模块，中间通过光纤传输，这样就可以远距离传输了。EDL301T的体积只有通常的光器件的1/6大小，PCB板设计可以做到很小。值得一提的是，该方案功耗很低，通常模块3.3V供电，需要100mA的功耗，此模块只需要30mA多的功耗，而其速率可以达到100Mbps，符合USB2.0的传输要求，图2为EDL301T的电路图。
图2： EDL301T的电路图
对于100Mbps以太网来说TX和RX差分线通常串0.1uF电容，对于1Gbps，通常差分线串0.01uF的电容。由于上述电路为LVPECL电平，LVPECL的输入是一个具有高输入阻抗的差分对，该差分对共模电压需要偏置到VCC-1.3V，这样允许的输入电平动态最大。对于LVPECL电平，我们通常用调整上下拉电阻来优化功耗，表3为LVPCL逻辑电平表。
表3：LVPCL逻辑电平表
通过上述设计，能够让USB传输100-120米，由于光纤传输损耗很小，信号传输非常稳定可靠。
在设计USB远距离传输的PCB板子时，建议采用4层板，这样对于100M传输更加稳定可靠。在滤波时，TX/RX电源最好单端滤波供电，这样对于EDL301T更加稳定，对于远距离传输也更加可靠。
