Page 3: Introduction
Introduction 1 Introduction The DS320PR412-421EVM features two DS320PR412 and two DS320PR421 linear redrivers that can extend the transmission distance of a PCIe Gen-5 x8 bus. The EVM can be directly plugged into a PCIe slot on a server or PC motherboard using the PCIe Edge connector on the board and paired with a PCIe add-in card using one of the two PCIe connectors on the EVM. -
