Hi Team,
Customer will use TUSB1002 for PCIE gen 1 re-driver, please help confirm TUSB1002 could compatible to support from PCIE Gen3 down to Gen1 function.
Because TI TUSB1002 datasheet didn't mentioned it to include PCIE Gen1,customer required TI to confirm, thanks.
"7.3.7 PCIe/SATA/SATA Express Redriver Operation (MODE = “R”; CFG1 = "0"; CFG2 = "0" ) The TUSB1002 can be used as a PCI Express (PCIe) Gen3, SATA Gen3, or SATA Express redriver. When TUSB1002's MODE pin = “R”, CFG1 pin = "0", and CFG2 pin = "0", the TUSB1002 will enable both channels (upstream and downstream) receiver and transmitter paths upon detecting far-end termination on both TX1 and TX2. Both upstream and downstream paths will remain enabled until EN pin is de-asserted low. All USB3.1 power management functionality is disabled in this mode. In this mode the TUSB1002 is transparent to PCIe link power management (L0s, L1) and SATA interface power states. Once far-end termination is detected on both TX1 and TX2, the TUSB1002 power will be at P(U0_SSP_1200mV) regardless of the PCIe or SATA power state. To save power during system S3/S4/S5 states it is suggested to de-assert the EN pin to conserve power."
