The U.S. government wants the Asian country to let its currency appreciate against the dollar to help reduce the growing trade deficit the U.S. runs with China. Recently, the Semiconductor Industry Association called on China to eliminate tariffs on chips imported into the country. For many electronics industry executives, China is a puzzle. It is a potential revenue generator and a definite strain on resources. Tapping China's low-cost manufacturing opp

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.
