5.3. Performance and Cost Considerations
- Intel recommends that you enable TX FFE to ensure better interoperability among various HDMI 2.1 devices. However, RX jitter tolerance does not account for FFE usage.
- You can increase the performance of RX equalization and reduce FPGA dependency by utilizing redrivers or retimers that can compensate for higher loss profiles.
- Although using external redrivers or retimers can help your design meet CTS compliance, you must ensure that the settings are able to meet the proprietary loss profile setup.
Note: The electrical validation optimization in this document does not cover non-Intel devices. If your profile setup is significantly different from what is shown here, use Link Tuning method to verify link integrity.
- For PCB designs that do not require Intel® Quartus® Prime compilation, you can refer to Channel Placement Tools (CPTs) specific to Intel® Arria® 10 or Intel® Stratix® 10, which allow you to allocate link topology by designated pinouts.
