    Hi Frank,

    For 10G-KR applications, transmitting and receiving entities need to exchange link training. As such device should be seamless or pass through link training signaling/sequences. DS125DF410 is a limiting device and does not allow these link training to pass through the device.

    Please consider DS100KR401 device for this application. Please below note link to this device design documents:
