About capacitor value for some power supply in i.MX6

Hello, all.

SABRE-SD board has 22uF capacitor for VDD_HIGH_CAP, NVCC_PLL_OUT pin.

But these pin are recommended a 10uF capacitor according to Design Checklist (IMX6DQ6SDLHDG_Rev1.pdf).

And it is written in checklist that operation cannot be guaranteed, if capacitance over 10uF.

Why SABRE-SD board has 22uF, and does SABRE-SD board not occurred problem so far?

 

Best regards,

Tomo
