Video: Startup's founder describes 'black silicon' Product News 2/5/2009 Post a comment James Carey, co-founder of SiOnyx, talks about "black silicon," a material he developed that boasts more than 100 times the sensitivity of silicon, detects energy from the ultraviolet to the short-wave infrared bands, operates at a low voltage bias and, at less than 0.5 micron, is extremely thin.
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.
