DS160PR410: the suggested longest trace

Part Number: DS160PR410

Hi team,

Could you advise the suggested longest trace length when using this device on a low loss material PCB (TU-872) ?

Best regards,

    Hello -

    Are you trying to use the DS160PR410 in a PCIe Gen-4 application or in a non-PCIe application?  If non-PCIe application, what is the datarate  you plan to use it at?

    The DS160PR410 can typically compensate for up to 18 dB of channel loss at 8 GHz.  I estimate TU-872LK would have about 0.9 dB/inch at 8 GHz (5mil trace width assumed).  Therefore, the DS160PR410 can compensate for the loss of about 20 inches of the 5mil trace  length that uses TU-872LK material.

    Regards,

    Davor
