Cypress/Lexmark to Display 66-MHz, Two-Layer Board At EMC Symposium; Cypress EMI Suppression Technology Enables Cost Breakthrough.

SAN JOSE, Calif.--(BUSINESS WIRE)--July 30, 1999--

Cypress Semiconductor (NYSE:CY) and Lexmark International (NYSE:LXK) today announced that they will be displaying a Lexmark Optra Se 3455 Laser Printer with a 66-megahertz data bus on a two-layer PCB board.

Cypress and Lexmark will be exhibitors at the IEEE EMC Symposium, August 2 through August 5 in Seattle, Washington.

Cypress will display its EMI-reducing Frequency Timing Generators in booth number 227, and Lexmark will feature Spread Spectrum Clock Generation technology in booth number 238.

Historically, systems utilizing a 66-MHz data bus required anywhere from four- to six-layer boards. Multi-layered boards were always needed to provide proper grounding for high-frequency, high-energy emitting designs and to ensure EMI suppression. Using Spread Spectrum technology patented by Lexmark and implemented by Cypress in its PREMIS(TM) products, Lexmark was able to go from a four-layer board to a two-layer board, significantly reducing the cost of the system. The spread spectrum technology reduces EMI energy by minimizing peak energy emitting points.

Designing this board so that it passed the FCC tests and functioned properly was not a trivial matter, said Dr. Keith Hardin, EMC engineer at Lexmark International. While it was not the only important factor, the spread spectrum timing technology implemented in FTGs by Cypress was an absolute necessity to making it successful.

Spread Spectrum Technology was adopted most rapidly by the PC market. However, there are many embedded computers, like those in laser printers, scanners, copiers, video games, and personal digital assistants (PDA), that are also rapidly increasing in performance and therefore generate increasing levels of electromagnetic interference, said Ian Chen, marketing director of Cypress's Timing Technology Division. Our PREMIS(TM) (Peak Reducing EMI Solution) family is helping designers to continually deliver increasing performance without the high cost and efforts related to EMI containment.

Cypress Frequency Timing Generators provide a proven and cost-effective method to reduce the peak EMI emissions at every harmonic simultaneously. Incorporating the most recent proprietary advances in the Spread Spectrum Timing Technology, including technology licensed to Cypress by Lexmark, Cypress Frequency Timing Generators provide optimum effectiveness by reducing EMI at its origin in the system timing path.
