Hello expert,

My customer is wondering if their circuit is correct or not. Could you double check below architecture is okay to use or not? Thanks!

Best regards,

Hi Ann,

What is the speed of the application? Assuming it is 25G from the SFP28 connector used, I would recommend using DS250DF410 instead: https://www.ti.com/product/DS250DF410

DS125DF410 does not have crosspoint mode to achieve the muxing shown in the diagram - DS250DF410 is capable of this.

If using DS250DF410 with crosspoint mode, please note signals can only be muxed within a 2x2 array of channels, e.g. RX[1:0] to TX[1:0], RX[3:2] to TX[3:2], ... .

Thank you,

Evan
