TUSB7340: Schematic review

Part Number: TUSB7340


Hi Sirs,

Sorry to bother you.

The PCIe to USB3.0 controller of TUSB7340RKMT is being used to transfer USB3.0*4 to the 4*LTE module of the back end.
The front end of the TUSB7340RKMT is a PCIe X1 Gen2 signals.

This  PCIE is  X1 Gen2 signals that are transferred out of the PCIe Switch by five sets of PCIE X1 Gen2.

If there is an LTE module that meets the CAT6 and above specifications, is there a Performance Issue?
Could you help review our schematic as below?

2.In view of the above problems, in order to meet the good performance of the back-end LTE module, is there any other solution?
