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.

Can I have this table by PCIe gen1 compensation value ?

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

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
