each VDD/GND set, one 0.1uf for low frequency and one 0.001uf for high
frequency noise on the power supply.
The PCB layout and power supply decoupling discussed above should
provide sufficient decoupling to achieve the following when measured at
the device: (1) The resultant AC noise voltage measured across each
VDD/GND set should be less than 100 mVpp, (2) All VDDs should be
within 50 mVpp of each other, and (3) All GNDs should be within 50
mVpp of each other.
