Hi,

We need the IEEE 1588 PTP PHY, that we search the DP83640 is the 10M/100M PHY in TI website, please kindly advise if there are any 10M/100M/1000M PTP PHY promotion, thanks.

    Hi Zhang Liang,

    We also have the DP83630 which supports IEEE 1588 PTP at 10M/100M.

    We do have a few devices which support SFD/SOF(Start of Frame Detection) which generate a signal when Start of Frame is detected. This is helpful for the MAC to eliminate the inaccuracy in time stamping caused due to the PHY. This is a feature which will be of a little help for MAC which runs the complete 1588 protocol.

    Here are devices that support SFD/SOF:

    DP83867 - 10/100/1000M

    DP83869 - 10/100/1000M

    DP83822  - 10/100M

    Best regards,

    Melissa
