Power Management Event:Open drain,active low.
     Used to reactivate the PCI Express slot's main power rails and reference clocks.

ISOLATEB

I

20

Isolate Pin:Active low.
     Used to isolate the RTL8111GS from the PCI Express bus.The RTL8111GS will not drive its PCI Express outputs(excluding LANWAKEB)and will notsample its PCI Express input as long as the isolate pin is asserted.

　　5 NET_PHY1000M_RTL8111GS IP注意事项

　　1、PCI Express 信号在PCB中走线时注意控制差分阻抗;

　　2、REGOUT信号是DCDC电路，尤其注意和RTL8111G芯片的区分，DCDC电路的电感之前不需要增加滤波电容;

　　3、以太网接口电路中，防静电处理使用高压电容即可，在PCB中注意布局和铺铜设计;
