2.1.3 Logic Schematics
Figures 2.1.2 and 2.2.5 detail the logic
schematics for the various circuits used in
the reference design.
2.1.4 Component Placement and Signal
Routing
Please refer to the Section 2.4 of this
document for more details on the placement
of components on the board. It is important
to provide very clean and adequate +5 V
and ground connections to the CS8900.
2.1.5 Bill of Material
Table 2.1 has a list components that are
typically used to assemble this adapter
card. For most of the components, there
are several alternative manufacturers.
