1. Consideration to design a PCB on the R9A02G011
It is necessary to have several considerations if design a PCB on the R9A02G011.
1.1 Analog input pin connection
Put 0.1 uF near each “ANI” pin individually (P20, P21 and P22 are ANI).

1.3 Decoupling capacitor and “VDD”, “REGC” and “REGCTX” power lines
Each Decoupling capacitor should be put on near each pin (VDD, REGC, REGCTX) individually.
Make these traces connected to "VDD", "REGC" and "REGCTX" thick enough. Because ""VDD", "REGC"
and "REGCTX" are power pins.
