The second round of testing was performed with an optimized revision of the deserializer hardware with the goal of isolating the high speed signal path from the ESD strike noise. The same initialization software was used as in the previous test to demonstrate the relative improvement from hardware alone. The addition of good layout practice and physical design considerations allows the system to achieve Class A performance at slightly higher levels than the baseline example.

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