    Greetings,

    DS125DF410 may lock to the data rate however this part has not been rated for KR applications. Please consider DS100KR800 device instead.

    Just to add some more detail, the DS125DF410 supports the KR/KR4 data rate (10.3125Gbps), but it does not support the auto-negotiation and link training protocol. If your system runs the KR/KR4 data rate but does not use auto-negotiation and link training, then the DS125DF410 can be used. If your system uses the auto-negotiation and link training, then the DS100KR800 and DS100KR401 family are a better fit, since they do support KR/KR4 auto-negotiation and link training.
