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.

1.1 Features

• PCIe x16 Riser Card option with four 8-channel unidirectional linear redrivers operating at rates up to 25

Gbps

• Linear equalization for seamless support of link training and PCIe channel extension
• CTLE boosts up to 18 dB at 8 GHz
• Programmable device configuration through GPIO or I2C, SMBus
• Onboard 12-V to 3.3-V, 2-A step-down DC/DC converter
• Industrial temperature range: –40°C to 85°C
• Flow-through layout in 5.5 mm × 10 mm, 64-pin, leadless WQFN 0.4-mm pitch package

1.2 Applications

• PCI Express Gen-1, 2, 3, and 4
• High-speed interfaces up to 25 Gbps
• Enterprise server motherboard, workstation
• Enterprise storage
• Enterprise add-in card, end-point
