DS125BR800: we want to get the configuration for 800 from the configuration of 820

Part Number: DS125BR800
Other Parts Discussed in Thread: DS125BR820,

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.

    Regards,

    Lee

  • hi team,

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

  • 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.
