Recommended Power Supply Decoupling Circuit
Figure 1 is the recommended power supply decoupling circuit configuration. 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 adjusted
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 part’s 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.
