Part Number: DP83867IR


Tool/software: Code Composer Studio

Does the DP83867IR have a register configuration for the RGMII 1000BaseT? On the other hand, the voltage measured on the differential signal line is 1.27v. Is this voltage normal?

    Hi sean,

    RGMII operation is controlled using register 0x0032 and 0x0086 in the DP83867.

    If, by differential signal line, you mean the channels of the DP83867 connected to the cable/RJ45 jack? Yes, 1.27V is a normal range. It should be right about the mid-point of the 2.5V input rail.

    Best Regards,
