Part Number: DP83TC813S-Q1
Other Parts Discussed in Thread: DP83TC811

Tool/software:

Hi! TI team,

We are planned to design an 100Mbps automotive ethernet based device. Can you please suggest a 100 Base-T1 compliant ethernet PHY ICs for our design from TI.

(Product catalogue may be better)

Thanks

    Hi Selvaganapthi,

    We don't have a formal catalog for our Ethernet products but the TI.com product table filtered for 100BASE-T1 PHYs should give you the equivalent overview.

    In layman's terms, I would say that the DP83TC812/813/814 family are popular general-purpose PHYs and have been on the market for some years. Compared to the basic 812, the 813 has a reduced footprint and the 814 has TC-10 features omitted. The DP83TC818/817 family is newer and supports advanced features such as time synchronization and security. The older DP83TC811 is not recommended for new designs. If you have other portfolio questions, I can put you in touch with our marketing team.

    Best,

    Hi Evan Su,

    Thanks for your support.

    We have one more clarification in DP83TC811(Though it is not recommended for new design). Can you clarify, what is the system (Number of transceiver) level difference between DP83TC811 and DP83TC813? because in documents related to DP83TC811, I could see 2/2 PHY transceiver but not in other variants of ethernet PHY ICs. 

    Thanks,

    Selva

    From a system perspective, all of our 100/1000BASE-T1 PHYs are point-to-point and have the same layout:

    So they each support a connection to one MAC device and a connection to one other PHY, on the TI.com product list I shared all PHYs are listed as "Single" for the "Number of ports" column. I'm not familiar with the "2/2 PHY transceiver" description for the DP83TC811 you mentioned, can you point out where you saw it? If it's a typo or ambiguity, I can ask our internal teams to review it.

    Hi Evan,

    Can you please clarify, why DP83TC811 part is not recommended for new design? Is it in EOL status?
    Also, I could see the DP83TC811 part is still active in TI website. Please clarify this also


     

    Thanks,

    It's not recommended for new designs from the perspective of our applications and marketing teams since it was our earliest 100M PHY product and many improvements have been made in the subsequent generations for easier design and debug while costing less. Officially it's not in EOL, but I don't have any reason to recommend it over the newer PHYs from the consumer's point of view or ours for new designs.
