Part Number: DS125BR800

hi team,

my customer has designed a board with DS125BR820 or DS125BR800, currently we have tested the 820, and we want to get the configuration for 800. Could you please help provide it? EQ:0x2F  VOD:0xAE  VOD_DB:0x82, Thanks.

  • Hi Frank,

    What type of configuration?  Pin levels?  EEPROM file?

    Thanks and Regards,

    Lee

    Hi Lee,

    Any is fine, they want to achieve the same function with 800. The EEPROM is better. Thanks.

    Hi Frank,

    Here is a low gain configuration to approximate the DS125BR820.

    hi team,

    if the customer only use the I2C, could you please share the configuration of the register? Thanks.

  • In reply to Frank Xiao:

    Hi Frank,

    Here are the register writes to make the same configuration in I2C.  Register 0x06 to enable SMBus access and then 3 registers per channel to set EQ, VOD and VOD_DB.
