(1) Supply noise testing was performed with minimum capacitors (as shown Figure 38 on the PCB). A sinusoidal signal is AC coupled from
DC to 10 MHz to the VDD11, VDD18, and VDDIO (1.8V / 3.3V) supply pins with amplitude of 25 mVp-p, 50 mVp-p, and 50 mVp-p / 100
mVp-p respectively measured at the device VDD pins.
