Question about DS110DF111EVM

Other Parts Discussed in Thread: DS110DF111EVM, DS125DF111EVM, DS125DF111, ALP, DS110DF111, DS100BR111

Hi, I'm disty of Japan area.
Please help me.

They try to boot from the EEPROM in DS110DF111EVM.
They try to operate DS110DF111EVM in SMBUS MASTER & EEPROM MODE.
Would you tell us the register settings(ROM data) at SMBUS MASTER & EEPROM MODE?

How can I set the address without register setting?

If you have a sample of ROM data, can I get it?

I'm waiting for your help.
Best regards.

  • Hi Ryuji-san,

    To boot from the SMBus in Master/EEPROM mode, you will need to leave the ENSMB pin floating. I am currently unable to find the user's guide for the DS110DF111EVM, but the DS125DF111EVM User's guide will be helpful, since it uses the same PCB layout (http://www.ti.com/lit/ug/snlu158/snlu158.pdf). This information is detailed on p. 7 of the User's Guide as well as p. 11 of the datasheet. Note that this is a setting for an input pin of the device, and setting up the DS110DF111EVM in EEPROM mode is not handled by a register setting.

    You can set the address on the DS110DF111EVM by manipulating the J16 and J10 pins as shown below:

  • Michael-san,

    Thank you very much for your help!!

    my customer followed your advice.
    But, They can not wake-up EVM from the EEPROM.

    Should they first set up the Register Address 0xFF?
    (P29 DS125DF111 see data sheet)
    Is it first ?

    What number should they input at non-description of Register Address?

    Best regards.

  • Hi Ryuji-san,

    When running the DS110DF111 in EEPROM (or SMBus Master) Mode, the device should immediately return to Slave Mode after the EEPROM parameters are loaded into the DS110DF111, so after EEPROM is read, the customer should be able to communicate with the EVM via a GUI like ALP. 

    Can you have the customer check a few things to ensure that the EEPROM is being read properly?

    Keep ADDR0 and ADDR1 pins floating on the EVM so that the address is set to default 0x30h. This is not a programmable address within the SMBus registers. The address is set manually via ADDR0 and ADDR1 pins on the EVM board.

    On the ADDR1/#DONE pin 10 of the DS110DF111, check to see if the output goes low to ensure that data from the EEPROM has completed being read.

    In the ALP GUI, the default channel that you will see on the "Channel Registers" tab is Channel 0, and you should be able to read directly from there without reading/writing to Register 0xFF. However, if you are running any script to program the EVM and not using ALP to change channel register values manually, you will need to set up the Shared Register Address 0xFF to talk to the desired channel.

    Thanks,

  • Hi Michael-san,

    I ask you on behalf of Asano-san. I'm his colleagues. I took over this matter from him.

    Do you have a following documents?

    Register map of DS110DF111 (ex: such as starting on page 22 of the data sheet of DS100BR111)

    Our customer wants us to provide them with some sort of documents / memos, even if not official ones.

    Best regards,

  • Hi Yoshihiro-san,

    I think one of my colleagues may have this register map that we can provide. I will let you know what I find out.

    Thanks,

    Michael

  • Micheal-san,

    I'm sorry for the delay reply.

    Thank you for your reply.

    Could you have the CTLE information about following questions?

    a) How much is the deviation when CTLE is same setting.

     My customer requests guarantee value. But I understand your information will be just a reference.

    b) Could you tell us the temperature characteristic for CTLE of this device?

     

    Best regards,

    Yoshihiro Hirata

  • Hi Yoshihiro-san,

    Thank you for your patience. I have been able to obtain some answers about CTLE variation. Please provide your e-mail address and I will forward the information to you off-line.

    Thanks,

    Michael
