Be Careful With Clock Demons! Your clock needs big and fast current transients from your power supply (typ. +3V or +5V). Think of fast as "with high frequency energy components." If you do not prevent it, current demand will flow through the power and ground buses. You can expect radiation or common impedance problems in such a situation (e.g., big loops or common GND layout with susceptible circuits).   Click here to read the complete article.

EDA Tools: Use the EDA Tools directory to find companies and their products within specific EDA disciplines.   Design Center Reference Library: This is your access point for lots of good information covering applications, design tools, consultants, intellectual property, trade shows, hot ICs and standards.
