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.

Table 5.  Link Budgeting Distribution
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)

Minimize lowest loss

Budgets for cable loss

3 HDMI cable → Connector → RX Redriver → FPGA RX 19 dB+10 dB

Better Redriver/retimer

Note: Refer to Table 7 for jitter tolerance data.
