11.7 Power Plane Partitioning
The power planes should be approximately illustrated in
Figure 6. The ferrite bead used should have an impedance
at least 75Ω at 100MHz. A suitable bead is the Panasonic
surface mound bead, part number EXCCL4532U or an
equivalent. A 10μF electrolytic bypass capacitors should
be connected between VCC and Ground at the device side
of each of the ferrite bead.
