1Overview
The PCIe Retimer AIC is mainly designed to bridge the connections between x16 PCIe
Slot host on Motherboard to 4 x4 NVMe SSDs on backplane. Alternately, the add-in-
card supports connecting to x8 or x16 devices as PCIe signal integrator.
The link speed of the HBA can support up to PCIe Gen3 speed, says 8Gb/s.
Considering the x4 NVMe application, it provides 3.2GB/s throughput for each x4
lane NVMe device.
To facilitate 4 x4 NVMe application, the motherboards have to support PCIe
bifurcation which divides x16 slot into 4 x4.
PCIe Retimer card plays the role to re-signal the PCIe signaling between root complex
and end devices to extend the distance between root and end devices.

3.3 Jumpers
•Jumper settings
JN1 is used for VPP0 and VPP1 configuration. Since come of the NVMe
controller’s LED management in VPP/I2C carry 2 slots information while some
are carry 4 slots information. JN1 is designed for users to select what types of
VPP protocol will be used in the application.
JN1: 1-3, 2-4 shunted means VPP0 and VPP1 is separated. (Default)
JN1: 3-5, 4-5 shunted means VPP0 and VPP1 is paralleled.

4Installation
4.1 Electrostatic Discharge Sensitive (ESDS)
Electrostatic Discharge (ESD) might damage electronic components. To prevent
your Retimer card from being damaged, it is important to handle it with care.
The following measures are generally sufficient to protect your device from ESD.
Precautions
•Use a grounded wrist strap designed to prevent static discharge.
•Touch a grounded metal object before removing the expansion card from
the antistatic bag.
•Handle the Retimer card by its edges only. Do not touch its components or
peripheral chips.
•Put the Retimer card back into the antistatic bags when not in use.
•For grounding purposes, make sure that your system chassis provides
excellent conductivity between the power supply, the case, the mounting
fasteners and the Retimer card.
