Full-year chip sales fell 9% in 2009, says SIA News & Analysis 2/1/2010 1 comment Global semiconductor sales were $226.3 billion in 2009, a decline of 9 percent from 2008 when sales were $248.6 billion, according to the Semiconductor Industry Association (SIA). The full-year decline was as had been expected in the last month but much less than had been predicted in the first months of 2009.
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.
