AM5726: Decoupling capacitors

Michael Shklyarman

Part Number: AM5726

Champs,

There are quite a bit of discrepancies in decoupling implementation (number of capacitors and their values) between AM5726 datasheet and IDK reference board, starting with VDD_CORE. Which one should be followed?

thanks

Hi Michael,

The device datasheet always takes precedence over existing EVM designs. The reason for this is that EVMs are designed very early and used for device validation, while the datasheet is regularly updated. There is also a very useful document covering PDN design and analysis: www.ti.com/.../spraby8.pdf
