ICS9148-10 Datasheet, PDF (11/12 Pages) Integrated Circuit Systems – Pentium/ProTM System Clock Chip

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 vias as
wide as possible to lower inductance.
Notes:
1 All clock outputs should have series
terminating resistor. Not shown in all
places to improve readibility of
diagram
2 Optional EMI capacitor should be
used on all CPU, SDRAM, and PCI
outputs.
3 Optional crystal load capacitors are
recommended.
