DP83822H: Inquiry for replacement parts

Jun wei Huang

Part Number: DP83822H

The original material LAN8720Ai-CP-TR (old) is replaced with DP83822H (NEW). What should I do with the extra pins?

(RMII)

Hi,

If you are using RMII mode, extra data pins ( RXD2, RXD3, TXD2, TXD3) can be left NC.

如圖所示，

因此，我使用RMII模式，將額外的數據引腳（RXD2，RXD3，TXD2，TXD3）連接到NC。這是正確的？

As the picture shows,

So, I used RMII mode to connect the extra data length (RXD2, RXD3, TXD2, TXD3) to the NC. this is right?

Yes, you can keep these not connected.
