1. All grounds must be electrically connected at the board level. For fpBGA packages, the total number of GND balls is less than the actual
2. NC pins should not be connected to any active signals, VCC or GND.
3. For package migration across device densities, the designer must comprehend the package pin requirements for the SERDES blocks. Spe-
