Business Editors/High-Tech Writers

MILPITAS, Calif.--(BUSINESS WIRE)--April 24, 2001

California Micro Devices Corporation (Nasdaq:CAMD) today announced that it has engaged IP licensing expert IDL to promote the EZTerm(TM) active termination patent of CAMD in selected markets worldwide.

When high-speed signals travel the wires (lines) in a system, the signals can become badly distorted if the lines are not properly terminated. This then creates ringing (noise) and radio frequency interference, leading to system errors and malfunctions. EZTerm(TM) is an active termination technique that addresses this problem. The new technology from California Micro Devices provides a circuit design that can be incorporated directly into the inputs or input/ outputs of integrated circuits, regardless of the operating voltage, technology level, or scaling employed.

David Lempert, President of IDL, said, "We are very pleased to be selected as the partner of California Micro Devices licensing of this exciting new patented circuit. Our analysis of the market shows a need for a solution to the ringing problems in high-speed circuits. Our success in patent licensing globally, coupled with CAMD's technical expertise, will allow the EZTerm(TM) technology to be applied broadly and effectively."

Charles Bellavia, Vice President of Marketing and Sales at California Micro Devices, said, "We are really excited about this new technology and the value it provides to IC and system designers. IDL has an outstanding track record of success worldwide in IP marketing. We look forward to a productive relationship with IDL as we help IC companies solve their circuit ringing problems."
