8.2 Typical Applications

The DS160PR810 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 DS160PR810 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 a number of DS160PR810 devices can be used to obtain signal conditioning for PCI Express buses of varying widths.

GUID-5FD194FF-BB64-4D72-9C0C-DB1582112E4E-low.gif Figure 8-1 PCI Express x4, x8 and x16 use cases using DS160PR810

Note all eight channels of the DS160PR810 flow in same direction. Therefore, if the device is used for dual x4 configuration with two devices, PD0 of both devices need to be connected together to implement PCIe state machine for first x4 link while PD1 for second x4 link.
