Part Number: TPS659037

Hello Ti,

This is Milav Soni From Teq Diligent, India.

We have build a custom board which have "AM5716AABCXA" processor and "TPS6590379ZWSR" PMIC available.

I have one question regarding designing.

As per H/W Designing of PMIC, There is 2.2-μF 6.3-V filtering capacitor near the OSC16MCAP pin.

Is this needed? is it compulsory?

If it is not than it can cause any problem in crystal functionality?

Please help me.

Thank You

Hello,

yes this cap is important. It is filtering the supply for the oscillator circuit.

Hello ,

Thank You For your reply.

Actually, Currently we have make a Board without capacitor, and it is running fine.

Is this dangerous for PMIC functionality?

Thank You

Hello,

It may run fine within some parts but you may face issue across different parts, over temperature or in noisy environment. It is a decoupling capacitor and it is recommended for installing it.
