8.2 Typical Applications

The DS160PR822 is a protocol and interface agnostic linear redriver that can be used in wide range of interfaces including:

  • PCI Express 1.0/2.0/3.0/4.0
  • Ultra Path Interconnect (UPI) 1.0/2.0
  • DisplayPort 2.0
  • SAS
  • SATA
  • XFI
The DS160PR822 is a protocol agnostic linear redriver with PCI Express receiver-detect capability. Its protocol agnostic nature allows it to be used in PCI Express x4, x8, and x16 applications. Figure 8-1 shows how eight DS160PR822 devices can be used to implement 2x2 crosspoint for x16 bus width to connect two CPUs to two EndPoints with flexibility.
