2.3.1.1 SerDes Core Power (SERDES_x_VDD)

  • 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 2-2. The capacitor pad to via trace must be as small as possible. At least one 0.1 μF and one 0.01 μF capacitors must be placed for each SerDes bank.
  • The bypass capacitor (10 μF) must be placed at the edge of the integrated circuit (IC).
