Recommended Power Supply Decoupling Circuit
Figure 1 is the recommended power supply decoupling circuit conï¬guration. It is recommended to put 0.1μF decoupling capacitors
on each VDD pins of our part, there are four 0.1μF decoupling capacitors are put in Figure 1 with an assumption of only four VDD
pins on our part, if there is more or less VDD pins on our Pericom parts, the number of 0.1μF decoupling capacitors should be adjust-
ed according to the actual number of VDD pins. On top of 0.1μF decoupling capacitors on each VDD pins, it is recommended to put a
10μF decoupling capacitor near our partâs VDD, it is for stabilizing the power supply for our part. Ferrite bead is also recommended
for isolating the power supply for our part and other power supplies in other parts of the circuit. But, it is optional and depends on the
power supply conditions of other circuits.
