AV9148F-53

Frequency Generator & Integrated Buffers for Mother Boards

Integrated Circuit Systems 

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.

ICS9148 - 53

Capacitor Values:

C1, C2 : Crystal load values determined by user

C3 : 100pF ceramic

All unmarked capacitors are 0.01µF ceramic
