6.3.3 PCIe/SATA/SATA Express Redriver Operation

When operating in a PCI Express (PCIe) Gen3, SATA Gen3, or SATA Express application, the SN75LVPE3101 enables both channels (upstream and downstream) receiver and transmitter paths upon detecting far-end termination on both TX1 and TX2. Both upstream and downstream paths remain enabled until the EN pin is deasserted low. In this mode, the SN75LVPE3101 is transparent to PCIe link power management (L0s, L1) and SATA interface power states. When far-end termination is detected on both TX1 and TX2, the SN75LVPE3101 power is at P(ACTIVE_1200mV) regardless of the PCIe or SATA power state. To save power during system S3/S4/S5 states, TI recommends to deassert the EN pin to conserve power.
