Proposal for SICOFI
4-μC Board Design
For a new layout design it is recommended to use a separate ground-layer which gives
the possibilty to connect all ground-pins of the SICOFI
4-μC (GNDA and GNDD) low-
ohmic together.
Furthermore, an optimum board layout should follow these recommendations
Separate all digital supply lines from analog supply lines as far as possible
Applying the standard practice regarding blocking capacitors is recommended
Place all SLIC circuits as close as possible to the Vinx/Voutx pins of the SICOFI
Separate all analog circuitry (especially SLIC and Vinx/Voutx) as far as possible from
any digital signal source (esp. clock signals)
Figure 28
Proposal for a ground concept
VDD is the grey colored layer and the Ground-plane is the black colored layer. The
Ground-plane should be on both sides of the board on the top and on the ground layer.
