4.3. System Link Budgeting Recommendations
Platform link budgeting helps improve your experience by allocating sufficient loss on main board (with Intel® Arria® 10 or Intel® Stratix® 10 FPGA), PCB panel or daughtercard, and HDMI connectors (including cables).
Apply a generic redriver primarily to meet Insertion Loss at 12 Gbps. In a typical use case scenario, there is an estimated cable loss of 19 dB with two connectors.
|Item||Link Component||Insertion Loss @12 Gbps||Comment|
|1||FPGA → FMC → TX Redriver||5 dB||TX FFE recommended|
|2||Redriver → HDMI connector||10 dB (+18 dB)||
