System ACE - What is the recommended capacitor bypassing for the System ACE CF controller chip?

説明

General Description: 

For the System ACE CF controller chip, what is the recommended number/placement of bypass capacitors?

ソリューション

1. One 0.1 uF capacitor per Vccl pin, placed as close as possible ( < 1cm). 

 

2. One 0.1 uF capacitor per Vcch pin, placed as close as possible ( < 1cm). 

 

3. Four 4.7 uF capacitors for lower frequency bypassing for Vccl (placed within a few cm). 

 

4. Two 4.7 uF capacitors for lower frequency bypassing for Vcch (placed within a few cm.. 

 

Since the controller chip is a TQ surface-mount part, placing the high-frequency caps directly underneath the package on the underside of the board is ideal and will save board space.
