Zynq-7000 SoC ZC706 Evaluation Kit - UG954 (v1.5) - Figure 1-32 C6 value and POR calculation is not accurate


In (UG954) (v1.5) ZC706 Evaluation Board User Guide, Figure 1-32 shows the PS Power On and System Reset Circuitry.


C6 is shown to be 270 pF, and the associated POR delay calculation uses this 270 pF value.

Is this POR calculation accurate?


The capacitor value for C6 is actually 5600 pF. This is clearly marked in the ZC706 rev 2.0 schematic.

Using the value 5600 pF for C6, the POR delay calculation then becomes:

C6 = 5600 pF; POR delay = 22.4 ms

Figure 1-32 will be updated in a future revision of (UG954).
