3 Test Setup and Results

Figure 3-1 shows a typical system setup with the DS160PR810EVM-RSC placed between a CPU on a server motherboard and an PCIe end point (Network Interface Card or NIC). Additional "Extender" cards are inserted to increase the channel loss and demonstrate the ability of the redriver to extend the reach.

Figure 3-2 is a typical test result achieved with a system shown in Figure 3-1. As the result indicates, the end point (Mellanox NIC) with the DS160PR810EVM-RSC placed in the datapath achieves a stable Gen4, x16 PCIe link.
