Micro-Electro-Mechanical Systems (MEMS) has a reputation of being one of those technologies that is always on the verge of taking off but somehow sputters. The truth is somewhat more complicated: Success varies widely depending on market segment. In this feature article, Jack Shandles gives us an update on MEMS.
Durable blue light emitter could boost OLED market
Product News  
7/6/2005   Post a comment
A durable blue phosphorescent organic LED developed by Universal Display Corp. has surpassed the 1,000-hour lifetime barrier by a wide margin.

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.
