Bulk bypass capacitors are required for moderate speed bypassing of the DDR SDRAMs and other circuitry. Table 1-2 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Table 1-2 only covers the bypass needs of the SoC's DDR PHY. Additional bulk bypass capacitance may be needed for other circuitry. For any additional decoupling requirements for the SDRAM devices, see the manufacturer's data sheet
