Hi Team,

When customer use the 954 and 913 series of pairs, they find such stripes appear. How could we analyze?

For map test, the signal margin is good.

    Hello,

    Are you able to check any of the status registers in the 954 listed below to see if errors are occurring?

    0x4D

    0x4E

    0x7A

    Another good way to test for errors is by using the Built-In-Self-Test internal to the 954 and 913.  This mode allows to test if errors are occurring in the system.  Section 8.4.5 of the 913 datasheet has information regarding how to use BIST to troubleshoot the system.  Additional information can be found in section 7.5.12 of the 954 datasheet.  

    Regards,

    Nick
