    Hello,
    I have some question about BCM53162 in "Web_Managed" version:
    1. Can we use BCM53162XMB1ILFBG for this?
    2. Do we need a license to use the "robo2_ROBO-OS_131.img" binary? I see a note about licensing before production on the bottom of page 7 from
    Robo2-RoboOS-PG131 reference guide.
    3. Where can we download the image files from?
    Thank you for your help,
    Sorin

    Hi Sorin,

    1.     Yes, you can use the BCM53162XMB1ILFBG

    2.     Yes, it requires license fee. Could you please contact with your local distributor support sales/FAE first? Then distributor support team will contact with our PLM for detail

    3.     Could you please double check with your local distributor support team to get the SW image support? It should be through you docSAFE account and need FAE to help apply for you.


    Thanks,
    Ryan

    Hi Ryan,

    One more question about BCM53162XMB1ILFBG in Web Managed configuration:
    If the management/setup was done on a previous power up session, and we don't need to monitor anything anymore, does the switch work without any intervention on the next power up (unmanaged like)?

    Thank you,
    Sorin

    Hi Sorin,

    Thanks the question.

    When BCM53162 is in web managed configuration it is running our RoboOS SW, and it requires the external serial flash device to store the RoboOS SW image for web managed configuration.

    Any management/setup configure in web managed operation will be store in file system of RoboOS SW image and will be kept for next power up.

     

    Thanks,

    Ryan

    Hi Ryan,

    We decided to go with the "High-speed Unmanaged" option for BCM53162.
    I would like to double check with you that BCM53162XMB1ILFBG can be used in this mode.
    Also, where can we get the software/firmware for this mode from?

    Thank you for your help,
    Sorin

    Hi Sorin,

    BCM53162XMB1ILFBG is for managed mode, not for unmanaged mode.

    And BCM53162 chip is only for managed mode sku, not for unmanaged mode.

    For BCM5316X 19x19 package, only BCM53161XUB1KLFBG is for unmanaged mode.

    Do you consider to use our RoboOS SW?

    For unmanaged mode, it still requires the external serial flash device to store the unmanaged SW image.

    For the SW image download, could you please double check with your local distributor support team? It may need sign certain doc such as SLA.. and it requires download through docSAFE and need FAE to help apply it for you.

     

    Thanks,

    Ryan

    Hi Ryan,

    We would prefer to use "High speed Unmanaged" mode, but as you said, it is available only for BCM53161XUB1KLFBG, which is commercial grade.
    We need "industrial grade" product and I guess we need to go back to "Web managed" option. The good news is that we can use the same schematic/PCB configuration (w. external serial flash), and function of sku and software used, we can have both options.
    Please let me know if we are right on this last assessment.

    Thank you for your help,
    Sorin

    Hi Sorin,

    Right, if your application needs "industrial grade" chip and it is a good approach.

    Please provide your schematic design for review when it is available.

     

    Thanks,

    Ryan

    Hi Ryan,
    I will send the schematic for review as soon as we have a draft.
    Thank you for all your help,

    Hello Ryan,

    We managed to finish the schematic for a "High Speed Unmanaged" or "Web Managed" switch.
    We will populate a BCM53161XUB1KLFBG for "High Speed Unmanaged" and a BCM53162XMB1ILFBG for the "Web Managed"(industrial grade).
    Because it is a "prototype development" we included all the parts to be able to change all the strap options, all the LEDs and other ways to test and see the best final version for our case.
    The schematic is attached.
    We really appreciate that you take the time to review our schematic.

    Thank you for your help,

    Hi Sorin,

    Sure, we will review your schematic file "10G_SW_BCM53162_REV-1".

    And will reply you the review comment by next week 10/3.

     

    Thanks,

    Hi Ryan,
    We really appreciate that you took the time to review our design.
    I still have a question about the 25MHz crystal that is supposed to be used: Can you recommend some parts?
    I cannot find any crystal to meet all requirements, especially the one that the equivalent resistance should be 15 ohms maximum.
    Thank you,
    Sorin

    Hi Sorin,

    Please refer to the TXC crystal part, TXC P/N is 7A25090002.
    Attach TXC 25MHz crystal information as below.

    Thanks,

    Ryan

    Hi Ryan,

    I am a little bit confused about the options for BCM53161/62.
    We designed the "High-Speed Unmanaged switch" using the BCM53161XUB1KLFBG.
    This is the only available option(of the series) for "High-Speed Unmanaged switch".
    On the data sheet is presented at page 59-60 the required configuration for  "High-Speed Unmanaged switch" with all 14 ports, including the 8 x 1G PHY.
    At page 15 it says that BCM53161 doesn't have the 8 x 1G PHY.
    Where is the mistake? A "High-Speed Unmanaged Switch" or "Basic Unmanaged Switch" are not possible to implement?

    Thank you for your help,
    Sorin

    Hi Sorin,

    Sorry to cause the confusing…

    1. For datasheet page15,

    BCM53162 is our superset chip including 8x1G gphy port support.

    Comparing with BCM53162, BCM53161 does not support 8x1G gphy port but other feature are the same with BCM53162.

    BCM53161 and BCM53162 are the same package and pin compatible.

     

    1. For datasheet page59-60,

    BCM53161 and BCM53162 could use our UM SW for unmanaged platform.

    As you know since BCM53162 chip feature is superset, customers mostly to use it as managed platform and we also recommend BCM53162 operate in managed mode per part number descriptions.             

             

    Since your design are using same common PCB board, it will be depended on your port configuration to place BCM53161 or BCM53162 and the corresponding SW.

     

    Please let me know if there is question.

     

    Thanks,

    Ryan

    Hi Ryan,

    Thank you for your quick response.
    So, to be clear for me, is it possible to use Robo2 Unmanaged Software with BCM53162XMB1ILFBG?
    This is the only SKU available for BCM53162 (data sheet page137) and is not included on the Supported SKUs for Robo2-UM.
    On the list of supported SKUs for Robo2-UM there are two BCM53162 SKUs that cannot be found anywhere else.

    Best Regards,
    Sorin

    Hi Sorin,

    By double checking in lab the UM SW also can use on BCM53162XMB1ILFBG – we have verified UM SW on our reference board BCM953162R with BCM53162XMB1ILFBG chip, it could boot up and tx/rx traffic.

    Right, the Robo2-UM support sku are match with our datasheet part number descriptions.  As I mentioned in last reply we recommend customer to use BCM53162XMB1ILFBG part on managed platform.

     

    Thanks,

    Ryan
