SN75LVPE802: SN75LVPE802RTJR EQ question

Part Number: SN75LVPE802

We have a customer design about PCIe gen1 and its loss is 7dB loss. We would like to know whether SN75LVP802 can support what dB level of compensation ?

Do you have PCIe gen1 EQ level tuning table ?

  • The 2.5 Gbps equalization is not specified. It would be approximately 6 dB when EQ = 1.

    Regards,

  • In reply to Lee Sledjeski:

    Can I have this table by PCIe gen1 compensation value ?

    or it is all the same dB value no matter its Gbps ?

  • In reply to Ray Lin:

    For 2.5Gbps the equalization table would be extended to look like below.

    The equalization provided by a CTLE circuit scales with frequency. 

    EQ        Gain

    NC         0

    0            2.5

    1            6

    Regards,
