Sinusoidal Input Amplitude
Duty Cycle
Fast/slow characteristic is selected per GPIO (where available) by “slew rate” control. See reference manual.
Use of GPIO in fast mode with the associated NVCC > 1.95 V can result in excessive overshoot and ringing.
Use of DDR Drive can result in excessive overshoot and ringing.
PA1
VDD is the supply voltage of CAMP. See reference manual.
This value of the sinusoidal input will be measured through characterization.
