Page 2: Introduction
All trademarks are the property of their respective owners. 1 Introduction The DS160PR810EVM-RSC evaluation module features four DS160PR810 linear redrivers that can extend the transmission distance of a PCIe Gen-4 x16 bus. It can directly be plugged into a PCIe slot on a server or PC motherboard using one end of the board, and paired up with a PCIe add-in card using the straddle mount connector attached to the other end of the board. -
