Part Number: DP83822I

Hi team,

My customer is evaluating KSZ8081 and DP83822I. Customer has a document that listed the link loss reaction time of KSZ8081 and DP83822I. It said KSZ8081 is 4.4us while DP83822I is 250us. So could you please help explain the meanning of  link loss reaction time and why we have worse spec. than competitor. Is this spec. critical to the system? Thanks.

Best regards,

Wayne

    Hello Wayne,

    I believe that you are talking about '8.4.11 Fast Link Down Functionality'. Please read this section of the datasheet and let me know if you need any further clarification.

    Additionally, what document are you referring to? Can you please provide me a link to it.

    Thanks,
