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-

cifically, the SERDES power pins of the largest density device must be accounted to accommodate migration to other smaller devices using
the same package. Please refer to TN1160,
