DP83822I: 4-level Strap pins

Brian Wang0928

Part Number: DP83822I

Customer would like to know is Table8-10 of the d/s with strap function that is applied for RMII and RGMII interface and is able to access the PHY address bit? Or is it applied for RGMII interface only?

Regards

Hi Brian,

I'm not sure I understand the question.

The Phy Address [PHY_AD0...PHY_AD4] is set by COL, RX_D0, RX_D1, RX_D2, and RX_D3.

RX_ER selects RGMII_EN

RX_DV selects RMII_EN

As seen in Table 8-13, RGMII_EN & RMII_EN should never both be pulled high.

Regards,

Alvaro
