3.1 Test Setup and Results

Figure 4-1 shows a typical system setup with the DS320PR410-RSC-EVM placed between a CPU on a server motherboard and a 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 3-1 Example Test Setup

Figure 4-2 is a typical test result achieved with a system shown in Figure 4-1. As the result indicates, the end point (Nvidia / Mellanox NIC) with the DS320PR410-RSC-EVM placed in the data path achieves a stable Gen5, x16 PCIe link.
