EL6731-0010 PLC主控模块

款低功耗单端口10/100Mbps以太网PHY。它提供通过标准双绞线电缆发送和接收数据或者连接到外部光纤收发器所需的所有物理层功能。此外，DP83822还可通过标准MII、RMII或RGMII接口灵活地连接到MAC。

DP83822的部分接收路径功能pin脚可以用bootstrap的方式将PHY配置为特定的工作模式，这些pin脚的电压值会在上电或者Reset的时候被检测到，从而完成PHY的配置。DP83822可以通过一个4电平的bootstrap电路来配置，bootstrap pin脚需要增加推荐值的上拉或者下拉电阻来设置电压，从而配置为某种特定模式。

下图是DP83822的bootstrap电路示意图，一部分bootstrap pin脚内置50kΩ的上拉电路，另一部分的bootstrap pin脚内置9kΩ的下拉电阻。通过外加上拉电阻RH和下拉电阻RL可将该bootstrap pin配置为特定模式。
