Are there general requirements for the decoupling capacitors on IOVDD like there are for many other pins on the ADuCRF101 (see the datasheet)?
Does the ADuCRF101 really need 8 decoupling capacitors in parallel? Instead of having 4 0.1 uF caps and 4 100 pF caps in parallel, why not just have 1 0.4 uF and 400 pF cap in parallel? If my memory serves me right, there are different valued caps in parallel because there are different frequencies of noise to suppress? I am a little new to picking out the right decoupling parts, but that is the only explanation or reason I can even remember that makes slight sense.
