8 Summary

System level ESD performance with FPD-Link is a function of both hardware and software design practice. At the hardware level, the design must incorporate shielding of the high speed signals, and strong grounding between the system enclosure and the PCB. From the software side, tools including FEC and LOCK detection tuning can be used to boost effective BER for the video path. The techniques described in this application note are targeted towards system level ESD testing, but the same practices can be applied to other noise injection EMC tests including BCI or radiated immunity to improve performance.
