TUSB1002A: PCIe/SATA/SATA Express Redriver Operation issue

Hi Sir,

      My customer is operating TUSB1002A in PCIe/SATA/SATA Express Redriver mode. 

      There are two use scenarios in their applications listed as below.

       1. HOST <-> TUSB1002A <-> M.2 with PCIe device

       2. HOST <-> TUSB1002A <-> M.2 with SATA devce

       The problem is that none of them the host could successfully detect the device.

       We have already checked the mode configuration (CFG1=0, CFG2=0, MODE=R), bus connections and the power.

       There seems to be nothing wrong.

       It would be kind of you to give us some directions. Will the EQ setting affect the detection?

        The customer said once bypass the redriver the SATA or PCIe device can be detected.

Thanks

Sincerely,

Edward
