CLOCK SYNCHRONIZER AND MULTIPLIER
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.
CLOCK SYNTHESIZER
Note: All clock outputs should have series terminating resistor. Not shown in all places to improve readibility of
