3.5 Core Voltage Decoupling
For module performance, decoupling capacitors are required to suppress the switching noise generated
by high frequency and to stabilize the supply voltage. A decoupling capacitor is most effective when it is
close to the device because this minimizes the inductance of the circuit board wiring and interconnects.
Table 3-5 summarizes the power supplies decoupling characteristics.
