Abstract :
As clock frequencies increase on digital equipment data buses, signal paths behave more like microwave striplines. It becomes ever more important to maintain bus impedance to prevent mismatches which can result in problems with false data and radiated noise. Series capacitors and resistors perform this function, Demands of miniaturization and improved manufacturing efficiency make a composite capacitor-resistor functional device attractive to designers. This paper describes the application in detail, and summarizes the development of such a composite device. Performance is compared to discrete devices in the same application. Future plans for expansion of the product series are described
