IT spending dearth mars 2003 chip outlook
News & Analysis  
3/3/2003   Post a comment
Optimism for a significant rebound in corporate IT spending in 2003 has begun to wane, leading analysts to rethink their forecasts for the semiconductor market.

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.
