8.2 Typical Applications

The SN75LVPE4410 is a PCI Express linear redriver that can also be configured as interface agnostic redriver by disabling its RX detect feature. The device can be used in wide range of interfaces including:

  • PCI Express
  • SATA
  • SAS

The SN75LVPE4410 is a protocol agnostic 4-channel linear redriver with PCI Express receiver-detect capability. Its protocol agnostic nature allows it to be used in PCI Express x2, x4, x8, and x16 applications. Figure 8 shows how a number of SN75LVPE4410 devices can be used to obtain signal conditioning for PCI Express buses of varying widths. Note all four channels of the SN75LVPE4410 flow in same direction. Therefore, if the device is used for x2 configuration, careful layout consideration is needed. In x2 configuration, the two-channel grouping can be used for PCIe receiver detect. PWDN1 pin puts channels 1 and 2, and PWDN2 pin puts channels 3 and 4 into standby.
