DP83867IS: DP83867ISRGZR and DP83867IRRGZ configuration table

Part Number: DP83867IS
Other Parts Discussed in Thread: DP83867IR

Hi Team,

Understand that they are both P2P but by looking at  DP83867ISRGZR and DP83867IRRGZ referring to different datasheet, and DP83867ISRGZR support SGMII.

The configuration table is different between DP83867ISRGZR and DP83867IRRGZ .

Please help to confirm: Will these difference in configuration affect the software?

Thanks.

    Hi Ernest,

    The default value for Reg 10h, bit 11 is 0 for DP83867IR. So just configuring Reg 32h, bit 7 is enough for RGMII mode. Similarly for DP83867IS, the SGMII_EN strap is controlled by LED_0 pin which is also default Pull Down (0), this shouldn't effect your software configuration as long as SGMII_EN strap is not enabled.

    Regards,
    Rahul
