Silicon Laboratories Names Andrew Krone and Augusto Marques as Engineering Fellows.

AUSTIN, Texas -- Silicon Laboratories Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive, mixed-signal IC innovation, today announced that Andrew Krone and Augusto Marques have been named as Silicon Laboratories Fellows in recognition of the significant contributions to the company's new product development through creative, breakthrough mixed-signal design.

Silicon Laboratories' Fellows Program recognizes the highest level of technical achievement and contribution by a Silicon Laboratories engineer. Silicon Laboratories' Fellows are selected based on proven mastery of multiple aspects of mixed-signal design, support for the mentoring and continuing education of the Silicon Laboratories technical team, significant contributions to the company's technology and a considerable, direct impact on business success through technical innovation.

"Andy and Augusto have both contributed significantly to the success of our core businesses. Andy's initial contributions to the design of the silicon DAA began a long list of innovations across multiple products in the modem and broadcast area," said Jeff Scott, Fellow and Silicon Laboratories co-founder. "Augusto has been instrumental to the success of our Aero([R]) transceiver family as an individual contributor and as a design team leader. Andy and Augusto's strong mixed-signal skills and many design contributions have directly resulted in commercial success for Silicon Labs."

Mr. Krone joined the company in 1997 and began work on the company's first product, the silicon direct access arrangement (DAA). Mr. Krone was also a vital member of the team that designed the ISOmodem([R]) embedded modem, which has captured approximately 50 percent share of satellite set-top boxes. In addition, Mr. Krone was part of the design team that developed RF techniques currently being applied in advanced broadcast products.

Prior to joining Silicon Laboratories, Mr. Krone was a design manager at Cirrus Logic where he was responsible for professional audio product development. He holds bachelor's and master's degrees in electrical engineering from the University of Illinois. Mr. Krone holds more than 27 issued or pending patents in the area of mixed-signal ICs.

Mr. Marques joined Silicon Laboratories in 1999 and was one of the first members of the Aero transceiver development team. Mr. Marques was the team leader on the Aero+ development and was the chief design lead on the Aero II development, the first single-chip CMOS GSM/GPRS transceiver. Most recently, Mr. Marques served as director of engineering for transceiver products and now serves as the head of Silicon Laboratories' Portugal Design Center.

Prior to joining Silicon Laboratories, Mr. Marques was an associate professor for electronics and physics at the University of Coimbra where he also consulted for silicon companies. Mr. Marques has a bachelor's degree in computer engineering and a master's degree in physics from the University of Coimbra, and a Ph.D. in microelectronics from the Katholieke Universiteit Leuven. Mr. Marques holds more than 16 issued or pending patents in the area of RF ICs.
