Part Number: DS80PCI810

Hi Team,

Actually, because the CPU update, now I am survey PCIE Gen4 redriver-DS160PR series.

I know retimer input and output are both 28dB. What is redriver input and output? input is 15dB or 28dB?

Thanks

    Hi Daniel,

    The location of this type of redriver is less critical.  To achieve 15 dB of channel extension I would recommend the redriver be placed at least 15 dB away from the system PCIe Tx.  This allows the Tx signal to attenuate so the redriver can recover the signal in a linear fashion.

    Regards,
