Application Information
1. Recommended Circuit Configuration
The power supply circuit of the optimal performance on the application of a system should refer to Fig. 2.
VDD decoupling is important to both reduce Jitter and EMI radiation.
The C1 decoupling capacitor should be placed, as close to the VDD pin as possible, otherwise the increased trace
inductance will negate its decoupling capability.
The C2 decoupling capacitor shown should be a tantalum type.
