TS3L110: Schematics and Layout Design Guidelines required

Part Number: TS3L110

Hi,

I am using TS3L110RGYR in my application. Can you please provide me the detail design guidelines, reference docs or application note. Do i need any external component to with the switch to switch between two LAN ports.

Regards,

    Hi Kamesh,

    No external components are required for operating the switch other than those components determined by your system. 

    Since the device is simply a switch a full design guide does not exist as it would vary due to system constraints. I have linked to a few E2E threads talking about  Magnetics and the TS3L110:

    e2e.ti.com/.../202408

    Also make sure to read up on TI's High speed layout techniques app notes. This is recently released one but there are numerous design recomendation guides out there.

    Hi Dakotah,

    Thank you very much for your reply. I just want to confirm that, i am using the switch after the RJ45 connector having in-build magnetics and before the Processor having two port of Ethernet Phy support. I want to switch between these two ethernet ports of processor. That is,

    RJ45 with magnetics -> TS3L110 switch -> Ethernet Phy on MCU/processor

    Will this be OK ?

    Regards,

    Hi Kamesh,

    I am not an Ethernet expert by any means but I do not see that causing an issue. To be sure I would continue to look at some other E2E threads to compare with your design. There are numerous posts regarding the TS3L110  as shown in the following E2E post:

    This post may have a similar concept to your design:

    Lastly, this E2E thread contains and app note for USB2.0 routing which operates in a similar frequency range.

    There is also a whole Ethernet forum where you will find existing posts that can help answer your question.
