问题：

这种信号放大器一般布置在哪里合适，比如我的控制器需要连到TBOX的USB接口，把TBOX当网卡用，

这个信号放大器目前布置在我的控制器端，这样是否合适？

帮忙审核一下原理图设计是否适当：

Hello,

Please send over the layout file, so we can look into this in more detail.

As for the schematic, we recommend removing the Common mode choke, as this can have a negative effect on the USB2 signal.

Additionally, this is more of a nitpick, please separate the ground being used for GND and VCC into two separate grounds.

Thanks,

Ryan
