2.3.1.2 SerDes I/O Power (SERDES_x_VDDAIO)

  • All decoupling capacitors (0.1 μF and 0.01 μF) are placed on the pad adjacent to the BGA via of the corresponding pin, as shown in Figure 2-1. At least one of the capacitors (0.1 μF and 0.01 μF) must be placed for each SerDes bank. The capacitor pad to via trace must be small.
  • The bypass capacitor (10 μF) must be placed at the edge of the IC.
