DS125BR401A OOB Pass Through

Hello,

             Could I know if we will let OOB signal pass through easily. How could we set register for OOB signal detect threshold level as below? Min or Max setting value is better. Thank you.

BR

    Hi Patrick,

    From our testing, the recommended setting for passing OOB signaling with the appropriate amount of start time and stop time is by setting SD_TH to F (or SMBus Assert Threshold = 00'b and De-assert Threshold = 00'b). In addition, please assure that the Signal Detect Threshold Register for the device (Reg 0x28) is set to its default 0x4C for optimal performance.

    Thanks,

    Michael
