DP83867CS: auto-polarity inversion of the MDI lanes

Arunkumar Palanisamy
Prodigy 10 points
Part Number: DP83867CS

Hi,

Does DP83867CSRGZR support auto-polarity inversion in the MDI lanes while working in 1Gbps ?

Where is it mentioned in the datasheet ?

Also please mention the conditions that has to be met for the PHY to be capable of handling auto-polarity inversion.

Thanks,

Arunkumar P

    Hi Arun,

    All PHYs that conform to IEE 802.3 spec will support this feature. It is part of the spec.

    The PHY will detect and correct polarity as needed per each channel. 

    Regards,
