Recommended Circuit Configuration
The power supply circuit of the optimal performance on the application of a system should refer to Figure 3.

DD
decoupling is important to reduce Jitter performance.
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.

Remark for use
Please do not use the pull-up resistance for the OUT terminal to prevent wrong operation of IC.
Please set the voltage of the PDWN terminal according to the following procedures when it is necessary to set IC
to power-down (standby) operation immediately after the start-up this IC.
1. Set the Hi level voltage when IC starts.
2. Set the Low level voltage after IC starts.
As this counter measures, we recommend the pull-up register that has been described to the above recommended
circuit to be added beforehand.
