1 Introduction
The DS160PR412-421EVM features two DS160PR412 and two DS160PR421 linear redrivers that can extend
the transmission distance of a PCIe Gen-4 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.
