EVAL-ADIN1100EBZ IEEE-1588 PTP

Category: Datasheet/Specs
Product Number: EVAL-ADIN1100EBZ

Hello,

I have a question regarding the IEEE-1588 time-stamp query Via the EVAL-ADIN1100EBZ .

I have 5 set of current drivers that are connected in a LINE topology using ADIN2111 MAC+PHYs. it means that every channel has its own MIC+ADIN2111 as interface. 

This modules responses based on a Query command relating to their MAC address so they can be connected in the BUS. It means that there is no collision because they don't communicate simultanously. 

They are connected in LINE topology and there are only 1 pair of SPE (single-pair-Ethernet) comes out from the module.

My customer has no SPE connector on-board and wants to use EVAL-ADIN1100EBZ as a media converter to convert SPE to simple 10base-T using RJ45.

We want to know if by using this EVAL-ADIN1100EBZ they also can request IEEE 1588 time stamp and do their synchronization with the software.

What I think is that This EVAL-ADIN1100EBZ is transparent to IEEE-1588 time stamp. on the other hand there is ADIN1100 on the board that doesn't support IEEE-1588 time-stamp. I'm confused

It would be very helpful if get your opinion also.

Thank you so much.

  • Hello Mehdi,

    The ADIN1100 and the ADIN1200 are Ethernet PHYs or transceivers (layer 1 in the TCP/IP stack), which means that they just receive/transmit a bitstream from/to the MII interface to the MDI interface. They are transparent to the content in the bitstream.

    In this particular case PTP is an application layer (layer 5) protocol, the ADIN1100 device in the EVAL-ADIN1100EBZ receives the bitstream through the T1L cable, and sends it through the RMII/RGMII interface to the ADIN1200 in the board, which then sends the data through the RJ45 connector, and vice versa.

    Regards,

    Raquel.
