Model : PCIe Retimer Card User’s Manual
PAGE 4 OF 7
Overview
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.
