4.3. System Link Budgeting Recommendation
Platform link budgeting helps improve your experience by allocating sufficient loss on main board (with Intel® Arria® 10 FPGA), PCB panel or daughtercard and HDMI connector (including cables).
Apply a generic redriver primarily to meet Insertion Loss at 12 Gbps. Cable loss estimated at 18dB includes 2 connector, in a typical use case scenario.
| Item | Link Component | Insertion Loss @12 Gbps | Comment |
| 1 | FPGA → FMC → TX Redriver | 5dB | TX FFE recommended |
| 2 | Redriver → HDMI connector | 10dB (+18dB) | Minimize lowest loss Budgets for cable loss |
| 3 | HDMI cable → Connector → RX Redriver → FPGA RX | (18dB+)10 dB | Better Redriver/retimer |
Note: Refer to Table 7 for jitter tolerance data.
