The final round of testing incorporated software optimizations to the deserializer initialization to further improve performance. The addition of tweaks to the LOCK sensitivity as well as the addition of FEC to the FPD-Link channel significantly improves the overall performance under transient ESD stress, and allows for achieving Class A performance under higher levels of ESD noise.

• Class A = No loss of LOCK, no uncorrectable CSI-2 errors.
• Class B = Temporary loss of LOCK or CSI-2 errors which automatically recover
