SN75LVPE802: Adaptive EQ tuning

Part Number: SN75LVPE802
Other Parts Discussed in Thread: DS80PCI810, DS125BR111

Hi,

Does SN75LVPE802 have adaptive EQ tuning feature for which it can adjust the EQ setting automatically based on the link training result between host and device?  If not, do we have any other PCIE redriver with such feature?

Thanks!

Antony

  • Hi Antony,

    I would recommend using the DS125BR111 or DS80PCI810 for PCIe links which use link training.  In either case the CTLE setting of the redriver is not adaptive, but the DS125BR111 has a linear output drive which is transparent to the PCIe Tx equalization.  This allows for the system components to make a more optimal training which includes the redriver compensation.

    Regards,
