Helle LEDs nicht nur für Autos News & Analysis 3/18/2005 Post a comment Vor allem für die Außenbeleuchtung von Fahrzeugen haben Agilent und Lumiled eine neue Familie von Leuchtdioden entwickelt. Die LEDs liefern einen besonders hohen Lichtstrom.
Bring Speed and Accuracy to 4-Port Models of 40-Gb/s Differential Structures Design How-To 3/9/2005 Post a comment Moving data at 40-Gb/s over copper is no longer a theoretical exercise; it has become a reality. For physical-layer structuresthe passive linear components, backplanes, IC packages, cables and connectorsare no longer the bottlenecks in high-speed digital systems. In this feature article, authors Jim Mayrand, Mike Resso of Agilent Technologies, and Dima Smolyansky of TDA Systems explore recent advances in 4-port instrumentation that now enable designers to accurately model 40-Gb/s dif
Optical receivers take the heat Product News 3/8/2005 Post a comment NEC introduces optical receiver modules designed for 10Gbits/s networks with the industry's highest heat tolerance and best-in-class sensitivity ratings for networks.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
