General Layout Precautions:
1) Use a ground plane on the top layer
of the PCB in all areas not used by
traces.
2) Make all power traces and ground
traces as wide as the via pad for
lower inductance.
Notes:
1) All clock outputs should have a
series terminating resistor, and a
20pF capacitor to ground between
the resistor and clock pin. Not
shown in all places to improve
readibility of diagram.
2) Optional crystal load capacitors
are recommended. They should be
included in the layout but not
inserted unless needed.
Component Values:
C1 : Crystal load values determined by user
C2 : 22F/20V/D case/Tantalum
AVX TAJD226M020R
C3 : 100pF ceramic capacitor
C4 : 20pF capacitor
FB = Fair-Rite products 2512066017X1
All unmarked capacitors are 0.01F ceramic
Connections to VDD:
= Routed Power
