Hi all
I'm using HW design checking list rev 3.0 and have question about it.
According to the No.2 of "Power and Decouple" section in schematic tab, there is a following requirement for VDD_SOC_IN.
VDD_SOC_IN requires 66μF of bulk capacitance because it supplies power for both VDD_SOC_CAP and VDD_PU_CAP.
I couldn't find it in datasheet so is this a new requirment for i.MX6 ?
Does the requirement mean that it requires 66uF in total ?

Hi Ko-hey
capacitors values are not defined in datasheet, as they are
chosen based on testing real boards. In attached part of Sabre reference
board schematic spf-27392 there are bulk capacitors (66uF in total)
and several decoupling capacitors (0.22)
Best regards
igor
