Figure 10: Example VSSA 0.020” Traces
In Figure 10, all components referenced to VSSA1 and VSSA2 have been placed and have been connected using
0.020” traces. Note that there are two separate traces, one for VSSA1 and one for VSSA2. Decoupling capacitors
C9 and C19 are as close as possible to their pins, as are VDDP decoupling capacitors C10 and C20. C10 and C20
should connect to the ground plane using two vias each.
