General Layout Precautions:
1) Use a ground plane on the top
routing 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
provisions for a 15pf capacitor
between the clock output and series
terminating resistor. Not shown in all
places to improve readability of
diagram.
2) Optional crystal load capacitors
are recommended. They should be
included in the layout but not
inserted unless needed.
