The Design Guide specifies that the AC coupling capacitors for all PCIe interfaces should have a value of 0.22uF, but I noticed that the P3768 reference design uses 0.1uF capacitors for the PCIe#1 interface (M.2 WIFI/BT). Is that a mistake in the design, or do certain devices need to use 0.1uF capac…

PCIe AC coupling capacitor size

0.1uF or 0.22uF for GEN1 and GEN2, 0.22uF for GEN3 and GEN4.
