BYPASSING SCHEME
For decoupling, best practice suggests that to preserve as much
of the plane-to-plane capacitance as possible, do not perforate
the planes for VSS and VDD. Secondly, it is advisable to decouple
VDD to VSS by using 0.1 μF high frequency ceramic capacitors.
The trace to the capacitor should be kept to an absolute minimum
length. It is recommend that one capacitor be placed in the
corner of the chip and one in the middle of each side for a total
of eight capacitors for VDD to VSS. Furthermore, decouple
IOVDD to IOVSS on each side of the device. It is recommended
that 10 μF tantalum or ceramic capacitors be used for low
frequency decoupling around the device. It is not important for
these capacitors to be close to the device.
