C1, C2, C3 = 5.6 pF
C4 = 10 nF
R1 = optional connect to ground via 0 W resistor.
R2 = optional resistor to ground to convert current into voltage
L1, L2, L3 = Optional inductors
1 nH … 10 nH, or microstrip lines with length 1 … 10 mm.
No inductors and directly connecting all supplies to V

might cause problems. The optimal values of the inductors
depends on the application board.
