8.2 Typical Applications

The DS320PR410 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 1.0, 2.0, 3.0, 4.0, and 5.0
  • Ultra Path Interconnect (UPI) 1.0 and 2.0
  • DisplayPort 2.0
The DS320PR410 is a protocol agnostic 4-channel linear redriver with PCIe receiver-detect capability. Its protocol agnostic nature allows it to be used in PCIe x4, x8, and x16 applications. Figure 8-1 shows how a number of DS320PR410 devices can be used to obtain signal conditioning for PCIe buses of varying widths.
