Dear sir

         we test new board which has DS100MB203, found that DS100MB203 not have output signal.  Use MCU to read DS100MB203 I2C is ok, but 10GKR signal is not link.

Do you meet  similar problem? Is there some solution to test it ? thanks.

    Frank,

    The output will be muted in low power mode.  Is the RESET pin driven Low?

    The resistor bypass scheme almost always causes issues at 10G datarate. 

    To enable the SMBus register control, Register 0x06 must be written to with the data 18'h.

    Regards,

    Lee
