DS250DF410: DS250DF410

Part Number: DS250DF410

Hello,

(1) I am looking a redriver/retimer for 25GKR backplane interface, can DS250DF410 support 25GKR interface?

(2) I plan to use SMBUS mater mode so I need to connect an EEPROM, is there any sample image available or any EEPROM part numbers recommended?

What will be the default value if EEPROM is empty?

thanks

      • The DS250DF410 meets the KR high-speed electrical requirements with ample margin
      • The DS250DF410 does not implement the optional link training feature. The local host should disable KR link training when implementing this retimer
    • (2) I plan to use SMBUS mater mode so I need to connect an EEPROM, is there any sample image available or any EEPROM part numbers recommended?
      • TI recommends to implement retimer Rx adapt mode 2 for applications with high insertion loss input channel to the retimer
      • Users may generate their own EEPROM images customized for their system using the the TI retimer GUI accessible via TI.com
      • Refer to the TI EEPROM application note per link below for recommendations
    • What will be the default value if EEPROM is empty?
      • refer to the DS250DF410 datasheet available on TI.com. The default register values per the datasheet are implemented if EEPROM is empty

    Thanks,

    Hello Rodrigo,

    Thanks for the reply, can you please give me the link for TI retimer GUI? I can not find it from TI.com.

    Also I check the EEPROM requirement, it has to be device address of A0.

    I checked the datasheet of below, there is no address byte, 1 0 1 0 x B1 B0 R/W, the B1 and B0 are for byte selection, is that OK to use?

    Hi,

    You may request download access to GUI via link below. The EEPROM part number per your message looks good to use.
