SN75LVPE4410: schematic

Part Number: SN75LVPE4410

Our customers have two questions as follows:

 Please help check the SN75LVPE4410 schematic as below and any need to adjust 

(1) Does SN75LVPE4410 Re-driver have the ability to enhance the Tx signal? If so, which Register should be adjusted first?

(2) From the test results below, we can see that using our CPU Tx-EQ Setting (DP: P1; UP: P4), all Re-driver CTLE Index test results are Fail ,

When RC uses the strength of Tx-Preset P1 (de-emphasis = -3.5 +/- 1dB), how to use Re-driver to enhance the signal quality?

p.s: The test for question 2 is to use the length of Figure 1.
