What is the function of the part HR682480E ?

[sangar]

Hi All,

I am doing reverse engineering a board in which I found a part HR682480E that is located near to Ethernet connector...I  don't see any datasheet is available there for this part...Could you let me know the purpose of this and any alternate?


Thanks,
Muthu
