8 Application and Implementation

Note

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The DS320PR810 is a high-speed linear repeater which extends the reach of differential channels impaired by

loss from transmission media like PCBs and cables. It can be deployed in a variety of different systems. The

following sections outline typical applications and their associated design considerations.

8.2 Typical Applications

The DS320PR810 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 DS320PR810 is a protocol agnostic 8-channel 4-lane 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 DS320PR810 devices can be used to obtain signal conditioning for PCI Express

buses of varying widths.
