An optimum system can be constructed by selecting an optimum host CPU and combining it

with the MSM6636B.

*1 Insert a capacitor between the power supply and GND to prevent supply noise.

It is recommended to connect a small-capacitance bypass capacitor and a large-capacitance

filter capacitor serially. The typical capacitors are as follows:

0.01 to 0.22 mF : Ceramic capacitor

10 to 100 mF : Tantalum capacitor
